A DISPLAY SYSTEM FOR A VIEWING OPTIC
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a non-provisional application of and claims priority to
U.S.
Provisional Patent Application No. 62/716,176 filed August 08, 2018, which is
incorporated
herein by reference in its entirety.
FIELD
The disclosure relates to a viewing optic with an integrated display system.
In one
embodiment, the viewing optic has an active display system that generates and
projects the
image into a first focal plane of the optical system. In yet another
embodiment, the disclosure
relates to a display system having one or more active displays.
BACKGROUND
Riflescopes have been used for well over a century and while the quality and
features of
these devices have improved tremendously over the years, the core components
(and the
limitations of those components) used in their design, manufacture and use are
still very much
the same today as they were 100 years ago. Riflescopes create a magnified or
unmagnified
image of a scene that is distant from the shooter on a focal plane, which is
coincident with an
aiming feature, or reticle. The reticle consists of wire or a material
deposited in a pattern onto a
glass surface and it is used as an aiming reference, which corresponds to the
trajectory of the rifle
to which it's attached. The reticle may also have specific features included
to aid the shooter in
making distance judgements and in compensating for bullet deviation at
different distances.
Turrets are also used to make adjustments to the reticle position in relation
to the target in
order to compensate for bullet deviation. This is a very developed and
reliable system that can
be used in the hands of the experienced and skilled shooter to make
challenging long range shots.
With the aid of a laser rangefinder (LRF) and a ballistic computer and careful
attention to detail,
an experienced shooter can routinely hit targets at the maximum effective
range of their firearm
by making the necessary mechanical adjustments to the firearm and/or executing
the correct
holds on the reticle pattern.
While this system performs well, there is always a desire to improve upon the
system. In
particular, there is a desire to reduce the complexity involved in hitting
long range targets. A
1
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
large amount of information is needed on a shot-by-shot basis in order to
effectively hit long
range targets and the shooter must be able to process this information and
make the correct
judgments and calculations in real time. In addition to the riflescope, other
tools are needed by
the shooter to ensure accurate shot placement. For instance, a bubble level
mounted externally to
the riflescope is needed to ensure that the optic is level before executing a
shot. This requires the
shooter to remove his head from the pupil of the optic to check his or her
level.
A laser rangefinder and ballistic computer are also needed to measure target
range and
calculate a bullet trajectory. This once again requires the shooter to attend
to an external device
and then remember the data when making the necessary adjustments. If a weapon
mounted laser
rangefinder is used, then the shooter needs to take special care to ensure
that the aiming point of
the optic is corresponding exactly with the aiming point of the LRF.
Additionally, and not trivial to the use of riflescopes, is that they are only
useful during
daylight hours. Once night begins to descend, thermal and/or night vision
devices must be
attached to the weapon in front of the riflescope. These devices capture other
forms of radiation
that are not visible to the human eye due to their wavelength or low
intensity. These devices
then either recreate the image of the scene or intensify it and reimage the
scene into the objective
of the riflescope. Effective and necessary for low light conditions, these
devices are also heavy
and large.
In the particular case of thermal imaging devices, a thermal scene is imaged
via infrared
optics onto a special thermal sensor. The image is then recreated on a micro
display and the
micro display is, in turn, reimaged into the objective of the riflescope with
a visible optics
system. The two separate optical systems required to accomplish this result in
a rather large,
heavy, and expensive device.
As technology advances, there is a need for some level of system integration
in order to
reduce the heavy processing requirements placed on the shooter. This
integration is also
required to decrease the "time to engagement" that is traditionally quite long
when multiple
devices have to be referenced and calculations and adjustments have to be
made. And finally,
the size and weight of additional devices needed for effective use of the
riflescope in low light
conditions can be reduced with a more integrated solution.
Previous devices have attempted to address some of these issues in different
ways with
varying degrees of success. However, all attempts prior have implemented their
solutions in the
2
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
Second Focal Plane of the optic. This is very disadvantageous because the
second focal plane in
a riflescope is only well correlated to the image of the scene at a single
magnification setting.
The location of the aiming point is only accurate at one location in the
turret adjustment as well.
Because of this serious limitation, additional electronics are necessary to
track the variables in
the rest of the system and adjust the aiming point accordingly. Other systems
provide
approximate aiming point solutions through the illumination of features at
generic, coarsely-
spaced intervals instead of having a quasi-infinite range of points to select.
Weaker systems are
only capable of displaying basic information such as distance to target or
current weather
conditions.
Thus, a need still exists for a viewing optic that can project information
into the first focal
plane of an optical system. The apparatuses, systems, and methods disclosed
herein address all
of these shortcomings in an innovative fashion.

DETAILED DESCRIPTION
The apparatuses and methods disclosed herein will now be described more fully
hereinafter with reference to the accompanying drawings, in which embodiments
of the
disclosure are shown. The apparatuses and methods disclosed herein may,
however, be
embodied in many different forms and should not be construed as limited to the
embodiments set
forth herein. Rather, these embodiments are provided so that the disclosure
will be thorough and
complete and will fully convey the scope of the invention to those skilled in
the art.
It will be appreciated by those skilled in the art that the set of features
and/or capabilities
may be readily adapted within the context of a standalone weapons sight, front-
mount or rear-
19
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
mount clip-on weapons sight, and other permutations of filed deployed optical
weapons sights.
Further, it will be appreciated by those skilled in the art that various
combinations of features and
capabilities may be incorporated into add-on modules for retrofitting existing
fixed or variable
weapons sights of any variety.
It will be understood that when an element or layer is referred to as being
"on",
"connected to" or "coupled to" another element or layer, it can be directly
on, connected or
coupled to the other element or layer. Alternatively, intervening elements or
layers may be
present. In contrast, when an element is referred to as being "directly on,"
"directly connected
to" or "directly coupled to" another element or layer, there are no
intervening elements or layers
present.
Like numbers refer to like elements throughout. As used herein, the term
"and/or"
includes any and all combinations of one or more of the associated listed
items.
It will be understood that, although the terms first, second, etc. may be used
herein to
describe various elements, components, regions, and/or sections, these
elements, components,
regions, and/or sections should not be limited by these terms. These terms are
only used to
distinguish one element, component, region, or section from another element,
component,
region, or section. Thus, a first element, component, region, or section
discussed below could be
termed a second element, component, region, or section without departing from
the disclosure.
Spatially relative terms, such as "beneath," "below," "lower," "above,"
"upper," and the
like, may be used herein for ease of description to describe one element or
feature's relationship
to another element(s) or feature(s) as illustrated in the figures. It will be
understood that the
spatially relative terms are intended to encompass different orientations of
the device in use or
operation in addition to the orientation depicted in the figures. For example,
if the device in the
figures is turned over, elements described as "below" or "beneath" other
elements or features
would then be oriented "above" the other elements or features. Thus, the
exemplary term
"below" can encompass both an orientation of above and below. The device may
be otherwise
oriented (rotated 90 or at other orientations) and the spatially relative
descriptors used herein
interpreted accordingly.
I. Definitions
The numerical ranges in this disclosure are approximate, and thus may include
values
outside of the range unless otherwise indicated. Numerical ranges include all
values from and
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
including the lower and the upper values, in increments of one unit, provided
that there is a
separation of at least two units between any lower value and any higher value.
As an example, if
a compositional, physical or other property, such as, for example, molecular
weight, viscosity,
etc., is from 100 to 1,000, it is intended that all individual values, such as
100, 101, 102, etc., and
sub ranges, such as 100 to 144, 155 to 170, 197 to 200, etc., are expressly
enumerated. For
ranges containing values which are less than one or containing fractional
numbers greater than
one (e.g., 1.1, 1.5, etc.), one unit is considered to be 0.0001, 0.001, 0.01
or 0.1, as appropriate.
For ranges containing single digit numbers less than ten (e.g., 1 to 5), one
unit is typically
considered to be 0.1. These are only examples of what is specifically
intended, and all possible
combinations of numerical values between the lowest value and the highest
value enumerated,
are to be considered to be expressly stated in this disclosure. Numerical
ranges are provided
within this disclosure for, among other things, distances from a user of a
device to a target.
The term "and/or" as used in a phrase such as "A and/or B" herein is intended
to include
both A and B; A or B; A (alone); and B (alone). Likewise, the term "and/or" as
used in a phrase
such as "A, B, and/or C" is intended to encompass each of the following
embodiments: A, B, and
C; A, B, or C; A or C; A or B; B or C; A and C; A and B; B and C; A (alone); B
(alone); and C
(alone).
As used herein, an "active display" comprises image-creating pixel modulation.
In one
embodiment, the active display is an emissive active display. Emissive active
displays,
including but not limited to Organic light-emitting diodes (OLED) and Light-
Emitting Diodes
(LED), feature the image and light source in a single device, and therefore an
external light
source is not required. This minimizes system size and power consumption,
while providing
exceptional contrast and color space. OLEDs are made from ultra-thin organic
semiconducting
layers, which light up when they are connected to voltage (charge carriers
become injected and
luminance mainly is proportional to the forward current). The major layers
comprise several
organic materials in sequence (for example, charge transport, blocking and
emission layers ¨
each with a thickness of several nanometers), which are inserted between an
anode and a
cathode. The terms "active display," "digital display" and "microdisplay" are
used
interchangeably.

Viewing Optic
FIG. 1A illustrates the traditional design of a riflescope, which is a
representative
example of a viewing optic. FIG. 1B illustrates an exemplary viewing optic 10
in accordance
with embodiments of the disclosure. Specifically, FIG. 1B illustrates a
riflescope. More
particularly, the riflescope 10 has a body 38 that encloses a movable optical
element 15. The
body 38 is an elongate tube tapering from a larger opening at its front 40 to
a smaller opening at
its rear 42. An eyepiece 56 is attached to the rear of the scope body, and an
objective lens 54 is
attached to the front of the scope body. The center axis of the movable
optical element defines
the optical axis 44 of the rifle scope.
An elevation turret 12 and a windage turret 48 are two dials that are often
found in the
outside center part of the body 38. They are marked in increments by indicia
20 on their
23
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
perimeters 11 and are used to adjust the elevation and windage of the movable
optical element
for points of impact change. These dials protrude from the turret housing 50.
The turrets are
arranged so that the elevation turret rotation axis 46 is perpendicular to the
windage turret
rotation axis 52.
FIG. 1C shows a cross-section view of the sighting device from FIG.1B with the
basic
components of optical system 14 and moveable optical element 15. As shown in
FIG. 1C,
optical system 14 includes an objective lens system 16, erector system 25, and
eyepiece lens
system 18. FIG. 1C shows a riflescope having a body 38, but optical system 14
could be used in
other types of sighting devices as well. Erector system 25 may be included
within a moveable
optic element 15. The erector system 25 may include a power varying lens
element or zoom
element 25A. In FIG. 1C, moveable optic element 15 also includes a collector
22, as well as
first focal plane reticle 55 and second focal plane reticle 57. When in use,
adjustment of turret
assembly 28 and turret screw 29 causes adjustment of moveable optic element
15.
The movable optical element 15 is adjusted by rotating the turret assembly 28
one or
more clicks. As the turret is rotated, a turret screw 29 moves in and out of
the scope, which
pushes the erector tube. The erector tube is biased by a spring so when the
turret screw is
adjusted, it locates the erector tube against the bottom face of the turret
screw. The erector tube
provides a smaller view of the total image. As the erector tube is adjusted,
the position of the
reticle is modified against the image.
A reticle is a circular, planar or flat transparent panel or disk mounted
within the scope
body in perpendicular relationship to the optical axis or line-of-sight
through the scope, and is
positioned between the objective lens element 54 and the erector lens element,
typically at a site
considered to be a front focal plane of the optical system within the housing.
In one
embodiment, the reticle contains fine etched lines or hairline indicia
comprising a center vertical
hairline and a center horizontal hairline, which orthogonally or
perpendicularly intersect at a
center point.
In one embodiment, as shown in FIG ID, the viewing optic can have a parallax
adjustment knob 70 or a focus knob. Parallax occurs when the optical plane of
the image of a
target is not coplanar with the optical plane of the image of the reticle. As
a result of the offset
between the two optical planes, the reticle can appear to move relative to the
target when the
marksman moves their eye around the center of the reticle. This parallax error
can result in a
24
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
shift in the point of impact from firing. The parallax adjustment of a viewing
optic enables the
marksman to eliminate optical error at different distances, by enabling the
optical system to be
adjusted to show the image of the target and the image of the reticle in the
same optical plane.
Parallax compensation changes neither the focus of the reticle nor the focus
of the image; it
simply moves the planes at which these two objects are in focus so that they
share the same plane
(are coincident).
As shown in FIG. 1D, the viewing optic can have a side wheel mounted to the
rotatable
parallax adjustment knob 70. The larger diameter of the side wheel provides
more space for
markers, such as range marker, to be applied, and is easier for the marksman
to rotate and read
when in use. The larger diameter of the side wheel serves to increase the
accuracy and resolution
of the range finding markers.
FIG. 1E shows a close-up view of an optical system 14 in cross-section,
illustrating how
light rays travel through the optical system 14. Optical system 14 may have
additional optical
components such as collector 22, and it is well known within the art that
certain components, such
as objective lens system 16, erector system 25, and eyepiece lens system 18
may themselves have
multiple components or lenses.
In one embodiment, the viewing optic can have a focusing cell having one or
more
adjustable lens for providing parallax adjustment. In one embodiment, the one
or more
adjustable lens is one or parallax lenses.
In one embodiment, a focus lens is located between an ocular lens and an
objective lens.

lens. The relative distance between the erector lenses and the objective lens
is adjustable, for
providing magnification adjustment.
III. Viewing Optic with an Active Display
In one embodiment, the disclosure relates to a viewing optic having an active
display that
generates a digital image and projects the digital image into the first focal
plane of the viewing
optic. In one embodiment, the disclosure relates to a viewing optic that has
an analog reticle and
a digital image, including but not limited to a digital reticle, visible to
the user when looking
through the viewing optic. In one embodiment, the viewing optic can be used
with an external
laser rangefinder with ballistic calculation capability.
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the viewing optic has a moveable erector tube with an
analog reticle
or a glass etched reticle that is mounted to the erector tube in such a way
that the analog or glass
etched reticle moves in conjunction with said erector tube. In one embodiment,
the digitally
injected reticle does not move in conjunction with the erector tube. Thus, the
digital reticle is
accurate regardless of the turret or erector tube position.
In one embodiment, the disclosure relates to viewing optic with a digital
display that can
be injected into the first focal plane of the viewing optic such that the
image of the digital display
on the first focal plane is not tied to the movement of the erector tube. In
one embodiment, the
display can give users accurate ballistic hold points of aim, regardless of
the erector tube/turret
position of the riflescope.
In one embodiment, the disclosure relates to viewing optic with an aiming
point that is
agnostic to the position of the erector tube and/or turret position of the
viewing optic. In one
embodiment, if a ballistically determined aim point is beyond the field of
view of the erector
unit, the turrets can be dialed to bring the ballistically determined aimpoint
into the field of view.
In one embodiment, the viewing optic has a main optical system comprised of an
objective lens system that focuses an image from a target down to a first
focal plane (hereafter
referred to as the "FFP Target Image"), followed by an erector lens system
that inverts the FFP
Target Image and focuses it to a second focal plane (hereafter referred to as
the "SFP Target
Image"), a beam combiner that is placed between the objective lens system and
the FFP Target
Image, an eyepiece lens system that collimates the SFP Target Image so that it
can be observed
by the human eye, and a second optical system.
In one embodiment, the second optical system has an active display, and a lens
system
that collects the light from the active display. The image from the digital
display is directed to
the beam combiner so that the digital image and the target image from the
objective lens system
can be combined at the first focal plane and viewed simultaneously. In one
embodiment, the
second optical system can have a reflective material, including but not
limited to a mirror.
Referring to the description above, the digital display is injected into the
main optical
system, between the objective lens system and the first focal plane, and then
is focused onto the
first focal plane. At the first focal plane, both the digital image from the
digital display and the
analog/glass etched reticle attached to the erector lens system share the same
plane. However,
the analog reticle is attached to a moveable erector lens system, while the
image from the digital
26
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
display is not. Therefore, if the erector lens system is moved, the analog
reticle will move, but
the digital image will remain stationary.
In one embodiment, the viewing optic can be rigidly mounted to a firearm. In
another
embodiment, a laser rangefinder can be mounted to either the firearm or the
viewing optic. The
laser rangefinder measures the distance to the target, computes the ballistics
for hitting that
target, provides that information into the active display so that the correct
point of aim can be
displayed with the point of impact of the rifle bullet.
It is important that the digital image remain stationary because the laser
range finder is
rigidly attached to viewing optic and its point of aim does not move. This
allows the digital
display to be digitally adjusted so that the digital laser designator
corresponds with the laser on
initial setup, and then the two will always remain in alignment, no matter how
the erector lens
system is moved.
Additionally, the barrel of a firearm is rigidly attached to the viewing
optic, so the point
of aim of the barrel never changes in relation to the digital display. This
allows the digital
display to be digitally adjusted so that a digital aim point corresponds with
the barrel of the
firearm at its initial "sight-in" distance during initial setup, and then the
two will always remain
in alignment.
When the need arises to shoot at different distances than the initial sight-in
distance, the
laser range finder can measure the distance and then do ballistic calculations
to determine the
new location of the point of aim. That new point of aim location is always
relative to the initial
sight in distance, so the riflescope simply needs to adjust the digital
display aim point to
correspond with the new point of aim.
A side benefit of this system is that, because the digital aim point is
stationary, the user
can easily test the accuracy of the turrets on the viewing optic that adjust
the erector tube
position using a reticle that has predetermined marks on it at regular
intervals. As the erector
tube moves, the reticle can be measured against the stationary digital aim
point to see if the
adjustment dialed on the turrets corresponds to the amount of movement
measured between the
digital aim point and the reticle attached to the erector lens system.
In one embodiment, the disclosure relates to a display system for a viewing
optic
comprising a first active display for generating a first image, and a second
active display for

In one embodiment, the disclosure relates to a viewing optic having a display
system with
one or more active displays. In one embodiment, the viewing optic has a
display system with a
first active display configured to generate an image and a second active
display configured to
generate a second image. In one embodiment, the first active display and the
second active
display are parallel in reference to each other. In yet another embodiment,
the first active display
is perpendicular to the second active display.
In one embodiment, the disclosure relates to a viewing optic with multiple
displays in
conjunction with a passive sight picture to provide clear resolution and
bright images to a user
regardless of the time or light conditions. In another embodiment, the
disclosure relates to a
viewing optic with a combination of thermal and night vision technologies to
be used in tandem
in order to optimize sighting pictures in all environments and scenarios.
In one embodiment, the disclosure relates to a viewing optic having an
integrated display
system with appropriate brightness and clarity levels for thermal technology
in a range of
environmental brightness levels.
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system that uses multiple displays to augment a passive image provided by a
day view optic.
Rather than projecting or displaying an entire image, the viewing optic with
an integrated
display system can use the thermal camera to augment a passive image rather
than display an
entirely new image. The ability to have two different displays also allows for
optimal battery life
while still providing sufficient brightness and image quality.
In one embodiment, the viewing optic with an integrated display system
combines
multiple displays into one viewing optic: a first display with high brightness
quality and a second
display with higher bit depth and higher resolution. In one embodiment, the
viewing optic has
two beam combiners. In one embodiment, the viewing optic has a first beam
combiner in the
main body and a second beam combiner in the base.
By using two displays, one display can be of the format that has low color
depth and
resolution, but high brightness for daytime use, and the other display can be
of the type that has
higher color depth and resolution, but lower brightness for low light use. In
one embodiment,
color depth, resolution and brightness can be a comparison between a first
display and a second
display. In another embodiment, the terms high color depth, low color depth,
high resolution,
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
low resolution, high brightness, and low brightness can be used in accordance
with industry
standards.
The advantage of the use of these two display types becomes clear when used
with
thermal and night vision cameras. In one embodiment, a thermal camera can be
attached to the
viewing optic and transmit a thermal image to the active display, which
transmits the image into
the field of view such that the thermal image is overlaid onto the passive
image.
During daylight, the passive image is bright, therefore the thermal image from
the active
display must be bright enough such that the user can see it. At the current
time, suitable displays
that have a high enough brightness for use in these conditions have low color
bit depth and lower
resolution (FIGS. 86 and 87). This means that there are fewer shades of color
available for the
display to project between lighter and darker areas and the quality of the
projected image is
lower.
However, if this display is only used during the day, it only needs to augment
the passive
image, so color depth and resolution is much less important. For example, the
sight can be
programmed to only outline thermal signatures, rather than shade them in,
since the passive
image will provide the necessary details needed for a good image and the
display will only help
draw the user's eye to a heat source.
During low light conditions, the passive image begins to dim to the point that
it becomes
harder for the user to see detail. In this case, a high brightness display
becomes unnecessary and
allows the use of another display that has lower brightness, but higher bit
depth and resolution.
In one embodiment, the viewing optic may have a light sensor that can detect
when light
levels go below a set threshold, the viewing optic uses the secondary display,
which could have
enough bit depth and resolution to accurately shade the heat source and
augment or replace the
passive image so that the user gets a clear image.
In another embodiment, a viewing optic with two or more active displays can
project a
thermal and night vision image into the field of view of the viewing optic. By
using both a
thermal camera and a low light camera, such as a low light CMOS, the two
active displays could
send an image from each camera into the field of view of the riflescope.
For example, the thermal camera could transmit outlines of heat sources to the
low bit
depth, low resolution display and the low light CMOS camera could transmit a
night vision
31
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
image to the high bit depth, high resolution display, so that both would be
simultaneously
imaged into the field of view.
Another advantage of a viewing optic with multiple active displays is that a
high
brightness display is a small display, which means it has a limited field of
view. For daylight,
this is not as big of a problem, because the user still has the ability of
seeing a wider field of view
from the passive optics. However, at night, when the passive image is less
usable, a small
display can become a liability for approaching threats. Fortunately, the lower
brightness display
is larger, so it allows a larger field of view for low light conditions. This
again allows for the best
of both worlds.
Lastly, high bit depth, high resolution displays use significantly more power
than a low
bit depth, low resolution display. This means that during daylight hours, only
the low bit depth,
low resolution display needs to be used and can significantly reduce overall
power consumption
than using a high resolution display all the time.
In one embodiment, the first and second active displays are configured to emit
light in a
direction that is substantially parallel to an optical axis of the viewing
scope. In yet another
embodiment, the first and second active displays are configured to emit light
in a direction that is
substantially perpendicular to an optical axis of the viewing optic.

image from the
second active display.

A. Main Body
In one embodiment, the main body is the shape of an elongate tube, which
tapers from a
larger opening at its front to a smaller opening at its rear and an eyepiece
attached to the rear of
the elongate tube, and an objective lens attached to the front of the elongate
tube. In one
embodiment, the first housing is a main body of a riflescope.
In one embodiment, the main body has a viewing input end, and a viewing output
end,
which can be aligned along viewing optical axis 44 (FIG. 1B), and can be
inline. Objects or
36
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
targets can be directly viewed by the eye of the user through the viewing
input end, along the
viewing direct view optics, and out the viewing output end. The main body can
include an
objective lens or lens assembly at the viewing input end. A first focal plane
reticle can be
positioned and spaced along the viewing optical axis A from the objective lens
assembly.
In one embodiment, a picture or image reversal lens assembly can be positioned
and
spaced rearwardly along the viewing optical axis A from the first focal plane
reticle. An erector
tube having an erecting image system is located within the main body between
the objective lens
and the ocular lens in order to flip the image. This gives the image the
correct orientation for
land viewing. The erecting image system is usually contained within an erector
tube.
The reversal lens assembly or erecting image system can comprise one or more
lenses
spaced apart from each other. The erector image system may include one or more
movable
optical elements, such as a focus lens that is movable along its optical axis
to adjust the focus of
the image and a magnification lens movable along its optical axis to optically
magnify the image
at the rear focal plane so that the target appears closer than its actual
distance. Typically, the
erector assembly includes a mechanical, electromechanical, or electro-optical
system to drive
cooperative movement of both the focus lens and one or more power-varying lens
elements of
the magnification lens to provide a continuously variable magnification range
throughout which
the erector assembly produces a focused, erect image of the distant target at
the rear focal plane.
Variable 'magnification can be achieved by providing a mechanism for adjusting
the
position of the erector lenses in relationship to each other within the
erector tube. This is
typically done through the use of a cam tube that fits closely around the
erector tube. Each
erector lens (or lens group) is mounted in an erector lens mount that slides
within the erector
tube. An erector sleeve attached to the erector lens mount slides in a
straight slot in the body of
the erector tube to maintain the orientation of the erector lens. The erector
sleeve also engages an
angled, or curving, slot in the cam tube. Turning the cam tube causes the
erector lens mount to
move lengthwise within the guide tube, varying the magnification. Each erector
lens will have its
own slot in the cam tube and the configuration of these slots determines the
amount and rate of
magnification change as the cam tube is turned.
An aperture in a second focal plane can be positioned and spaced rearwardly
along the
viewing optical axis A from the picture reversal assembly. An ocular lens
assembly can be
positioned and spaced rearwardly along the viewing optical axis A from the
aperture in the

CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the beam combiner can be a cube made of optical material,
such as
optical glass or plastic materials with a partially reflective coating. The
coating can be a uniform
and neutral color reflective coating, or can be tailored with polarizing,
spectrally selective or
patterned coatings to optimize both the transmission and reflection properties
in the eyepiece.
The polarization and/or color of the coating can be matched to the active
display. This can
optimize reflectance and efficiency of the display optical path with minimal
impact to the direct

error.
2. Parallax System
In one embodiment, main body has a parallax adjustment system. In one
embodiment,
the parallax adjustment system uses a device to connect a focusing cell to the
parallax adjustment
element.
In one embodiment, the viewing optic disclosed herein has a main body with a
focusing
cell located closer to the objective end as compared to a traditional focusing
cell and a beam
combiner located in a space traditionally occupied by the focusing cell. In
one embodiment, a
connecting element connects the focusing cell to a parallax adjustment
element.
In a typical riflescope, as depicted in FIG. 5A and FIG. 5B, the parallax knob
510 is
connected to the focusing cell via a simple cross pin 520 that rides on a cam
groove 530 in the
parallax knob, converting the rotational motion of the knob into linear motion
within the
focusing cell. However, in some embodiments disclosed herein, the focusing
cell is shifted
41
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
toward the objective side, and thus, a connecting device is needed to connect
the focusing cell to
the parallax adjustment element.
The parallax adjustment system can eliminate or reduce parallax error between
the image
of the active display and a reticle in the main body of the viewing optic. The
parallax adjustment
system disclosed herein allows for a viewing optic having a digital display
image and an image
of an outward scene integrated into a first focal plane (FFP) of an optic
system without parallax
error.
In another embodiment, the focusing cell is located closer to the objective
side of the
main body as compared to the focusing cell of a traditional riflescope. In one
embodiment, the
focusing cell is shifted from about 5mm to about 50 mm closer to the objective
as compared to a
focusing cell of a traditional riflescope. In one embodiment, the focusing
cell is shifted at least
20 mm closer to the objective as compared to a focusing cell of a traditional
riflescope. In one
embodiment, the focusing cell is shifted at least 10 mm closer to the
objective as compared to a
focusing cell of a traditional riflescope. In yet another embodiment, the
focusing cell is shifted
no more than 50 mm closer to the objective side as compared to a focusing cell
of a traditional
riflescope. In one embodiment, the focusing cell is shifted 30 mm closer to
the objective
assembly as compared to a the location of a focusing cell in a Vortex
Diamondback riflescope,
Vortex Viper riflescope, Vortex Crossfire riflescope, Vortex Razor riflescope.
In one embodiment the focusing cell is shifted closer to the objective as
compared to a
focusing cell of a traditional riflescope including but not limited to 15, 16,
17, 18, 19, 20, 21, 22,
23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, and 40 mm
closer to the
objective side of the viewing optic.
In one embodiment, a device connects the shifted focusing cell to the
adjustment knob.
In one embodiment, the device allows for the remote location of the parallax
adjustment lenses
located in the focusing cell. In one embodiment, the mechanical device is a
push-rod, a rod, a

FIGS. 5C-5F are representative schematics of a parallax adjustment system in
the main
tube 210 of a viewing optic according to one embodiment of the disclosure. As
shown in FIG.
5C, a device, such as a rod or shaft, 530 connects the focusing cell (parallax
lenses) 535, which
have been moved closer to the objective end of the viewing optic, to a
parallax cam track pin 540
within the parallax adjustment knob assembly. The shifted location of the
parallax lenses
provides the necessary space for the prismatic lenses forward of the first
focal plane. One end of
the connecting rod is coupled to the focusing cell and the other end of the
connecting rod is
coupled to a cam pin.
FIG. 5D shows the device 530 connecting the focusing cell 535 having the
parallax
lenses to the parallax cam track pin 540, which rides in the cam track 545 of
the parallax
adjustment assembly 550. In one embodiment, the parallax adjustment assembly
550 has a
rotatable element to move the cam pin and adjust the parallax lenses.
As shown in FIG. 5E, in order to provide space in the main body of the viewing
optic for
the beam combiner (prismatic lenses), the focusing shell is shifted closer to
the objective
assembly. Thus, a mechanism is needed to connect the focusing cell to the
parallax knob
assembly. A connecting device 530 connects the focusing cell to a cam pin 540
that rides in a
cam groove of the parallax knob assembly 560.
As shown in FIG. 5F the cam pin 540 rides in a cam groove 545 of the parallax
knob
assembly 560, allowing adjustment of the focusing cell via the parallax knob
assembly.
In one embodiment, the shifted focusing cell, which has the parallax lenses,
in the main
body provides space to integrate a beam combiner ahead of a first focal plane
of the objective
system.
In one embodiment, the beam combiner in the main body of the riflescope
disclosed
herein is located in the space where the focusing cell is typically mounted in
a traditional
riflescope.
In one embodiment, the disclosure relates to a viewing optic comprising: (a) a
main tube;
(b) an objective system coupled to a first end of the main tube; (c) an ocular
system coupled to
the second end of the main tube, (d) a focusing cell located between the
objective system and a
beam combiner, wherein the beam combiner is positioned between the focusing
cell and a first
focal plane reticle; and (e) a rod connecting the focusing cell to a parallax
adjustment element.

WO 2020/101768 PCT/US2019/045493
In one embodiment, the rod connects the focusing cell to a cam pin of the
parallax adjustment
element. In some embodiments, the parallax adjustment element has a knob.
3. Magnification Tracking System
In one embodiment, the disclosure relates to viewing optic and methods for
tracking the
magnification setting of a viewing optic, wherein the components of the
tracking mechanism are
reliable, completely transparent to the operator, and environmentally
protected.
When a reticle is in the first focal plane, the reticle is in front of the
erector system and
thus the reticle changes proportionally with the change in lens position
creating a magnified
image. The erector system changes position through the use of a magnification
ring that is
located on the external portion of a rifle scope near the ocular housing.
Typically, a
magnification ring is connected with a screw to an outer erector sleeve,
forcing the outer erector
sleeve to rotate with the magnification ring when rotated causing cam grooves
to change the
position of the zoom lenses located in the erector system. When projecting a
digital image onto
the first focal plane it is necessary to scale that image with the scaling of
the reticle to make the
digital image usable.
The magnification adjustment mechanism is coupled to the power-varying lens or
zoom
lens element, which provides the ability to adjust an optical magnification of
the image of the
distant object.
In one embodiment, and as shown in FIG. 6, a potentiometer wiper 610 is
located on the
outside diameter of an outer erecter sleeve 620. The potentiometer wiper
contacts a membrane
potentiometer 710 located on the internal diameter of the main body 210 of the
riflescope (see
FIG. 7).
As shown in FIG. 8, in one embodiment, the potentiometer wiper 610 is a flat
spring with
two points of contact to insure it maintains contact with the membrane
potentiometer 710. The
flat spring is located between the outer erector sleeve 620 and inner erector
tube. The
potentiometer wiper 610 is located on the inside diameter of the riflescope on
the opposing inner
wall of the magnification ring slot screw 820. The potentiometer wiper 610 is
fastened to the
side inner side of the scope tube using adhesive.
In one embodiment, the potentiometer wiper has the ability to lay completely
flat on the
outside diameter of the outer erector sleeve. In one embodiment, the
potentiometer wiper is
placed internally on the outer erector sleeve.
44
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the potentiometer wiper is not placed on the magnification
ring 810
of FIG. 8.
The magnification tracking system disclosed herein is located internally and
no part is
exposed to the environment, which offers a few advantages. First, the system
is internal
resulting in no seals being needed to protect the wiper/erector system from
the environment.
Secondly, magnification tracking system is completed when the erector system
is installed into
the riflescope. This eliminates the possibility for debris to enter the system
through a screw hole
on the exterior of the magnification ring.
In one embodiment, the disclosure relates to a system for tracking
magnification setting
of a viewing optic, wherein the system uses a sensor and a material that has
varying degrees of
optical reflectance/absorption. In one embodiment, the sensor is located in a
base of a viewing
optic, wherein the base couples to the main body of the viewing optic, and the
material is located
in the main body of a viewing optic.
In one embodiment, the disclosure relates to a viewing optic having a main
body
comprising an erector tube with an erector lens system, a cam tube or sleeve
surrounding or
encapsulating the erector tube, a material with varying degrees of optical
reflectance/absorption
coupled to the cam tube and a base coupled to the main body, wherein the base
has an integrated
display system and a photosensor for detecting optical reflectance/absorption
from the material.
In one embodiment, the base has a printed circuit board or microprocessor for
communicating
with the photosensor and one or more microcontrollers or electronic
controllers.
In one embodiment, the viewing optic has a main body with a magnification
adjustment
ring for adjusting an optical magnification of an image, and a base coupled to
the main body
having an integrated display system, a micro-processor, and a system to
deliver the
magnification setting of the optic to the microprocessor, wherein the
microprocessor
communicates with the active display of the integrated display system.
In one embodiment, the disclosure relates to a system for tracking
magnification setting
of a viewing optic with no mechanical link between the moving parts of the
opto-mechanical
system and the sensing device. The magnification tracking system disclosed
herein is embedded
in a base coupled to the main body of the viewing optic and does not have a
mechanical link
between the stationary and the moving parts of the system.

In one embodiment, the disclosure relates to a viewing optic having a main
body with an
erector tube housing an erector lens assembly and a cam sleeve surrounding the
erector tube and
having a material with varying degrees of optical absorption/reflectance and a
base coupled to
the main body, wherein the base has a photosensor. In one embodiment, the
material with
varying degrees of optical absorption/reflectance surrounds the cam sleeve at
the end of the cam
sleeve near the magnification adjustment ring of the main body. In one
embodiment, the
photosensor is located beneath the material with varying degrees of optical
absorption/reflectance on the cam sleeve.
When the magnification adjustment ring 212 of the viewing optic is rotated by
the
operator/user, the outer cam sleeve is rotated, which moves two lens cells,
thereby changing the
effective optical magnification of the riflescope.
In one embodiment, the cam sleeve has material with varying degrees of optical
reflectance/absorption. In one embodiment, the material is affixed to the
outer diameter of the
cam sleeve.
In one embodiment, the material is a strip of material. In one embodiment, the
material is
approximately 10 mm wide and 40 mm long. In one embodiment, a first side of
the material has
an adhesive that is used to attach it to the outer cam sleeve. In another
embodiment, the other
side of the strip has a printed grayscale gradient on it, such that when an
LED is directed to it,
varying amounts of light are reflected depending on the portion of the
gradient being exposed to
the LED.
In one embodiment, the PCB has an LED and a photosensor. In one embodiment,
the
LED and photosensor are located directly beneath the gradient strip, which is
attached to the
outer diameter of the outer cam sleeve. The LED illuminates the gradient strip
and the
photosensor receives a portion of the light reflected off the gradient strip,
which can then send a
signal to a microcontroller, wherein the strength of the signal varies with
the amount of light
detected.
When the magnification adjustment ring is rotated by the operator a different
portion of
the gradient strip is exposed to the LED and photosensor, which in turn
changes the signal
strength sent to a microcontroller. The optical magnification setting of the
system is therefore
able to be tracked by associating it with the amount of light detected by the
photosensor.

position of the
reflective gradient material that is attached to the outer cam sleeve in the
main body. The outer
cam sleeve and associated optical system is hidden in this image.
FIG. 68 is an exploded view of printed circuit board 6710 the photosensor and
LED 6720
with a simulated cone of vision drawn to illustrate the angle of acceptance of
light for the
photosensor.
FIGS. 69 and 70 are images of the photosensor and LED 6720 working in
conjuction
with the reflective gradient strip 6910 that is attached to the outer cam
sleeve 6610 to measure
the magnification setting of the optic. This illustration shows a gradient
strip 6910 that has 4
specific sections of differing reflectivities but it should be noted that this
strip could be infinitely
varying in its reflectivity. The gradient strip 6910 couples to the cam sleeve
at a portion of the
cam sleeve located near the magnifcation adjustment ring. The printed circuti
board 6710 is
located in the base 6505 that couples to the main body of the viewing optic.
The LED and
photosensor 6720 on the PCB 6710 are located below the gradient strip 6910.
In one embodiment, the disclosure relates to a viewing optic comprising: a
main body
with a first end and a second end and having a center axis; an objective lens
system disposed
within the body; an eyepiece lens disposed within the body; an erector tube
disposed within the
main body and having an erector lens system; the objective lens system,
eyepiece lens, and
erector lens system forming an optical system having a first focal plane and a
second focal

second focal plane
proximate the eyepiece lens; a cam sleeve surrounding the erector tube that
moves in
conjunction with a magnification adjustment ring for adjusting the optical
magnification of an
image, a material with varying degrees of optical absorption/reflectance that
is coupled to the
cam sleeve; and a base coupled to the main body and having a photosensor that
detects the
47
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
light from the material, a microprocessor in communication with the
photosensor, and an
active display in communication with the microprocessor that generates an
image based on the
magnification setting and projects the generated image into the first focal
plane of the viewing
optic. In one embodiment, the generated image from the active display is based
on the signal
obtained from the photosensor.
Delivering the magnification setting to the microprocessor has many benefits
including
but not limited to changing a reticle pattern based on a magnification
setting, and changing the
font size of alpha-numeric information automatically as magnification changes.
In addition, if
multiple display "pages" are stored in a memory system, the micro-controller
can automatically
switch between the "display" pages depending on the magnification setting in
order to present
the operator with the most relevant data.

data may include,
49
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
for example, calibration data, a ballistic profile lookup table that cross-
references rotational data
and/or linear data with shoot-to-range values, rifle data, projectile data,
user data, etc.
The sensor(s) 912 may be used to sense any of a variety of environmental
conditions or
characteristics associated with the use of the riflescope. For example, the
sensor(s) may sense
atmospheric conditions (such as humidity, temperature, pressure, etc.),
inclination, rifle cant,
and/or the sight direction of the rifle (compass direction). Any number of
sensors may be
included. Sensor data may be recorded by the processor and saved into the
memory and/or used
in the processing of instructions for operation of the viewing optic.

of the riflescope to
form a totally enclosed and integrated system.
In one embodiment, the base and the main body of the scope are an enclosed,
integrated
system. In one embodiment, the base is coupled to the main body without the
use of clamps,
which are designed for easy removal.
In one embodiment, a viewing optic, which has a main body and a base coupled

embodiment, the
51
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
top side of the base couples to a lateral split in the bottom-side of the main
body of a viewing
optic
In one embodiment, the base comprises an integrated display system for
generating
images with an active display and directing the images along the display
optical axis for
simultaneous overlaid viewing of the generated images with images of the
outward scene,
wherein the generated image is injected into the first focal plane of a main
body of a viewing
optic.
In one embodiment, the base is separate and distinct from a laser rangefinder
device. In
one embodiment, the base is an independent apparatus from a laser rangefinder
device.
In one embodiment, the second housing or base is not an add-on accessory. In
another
embodiment, the second housing or base is not coupled as an add-on accessory
adjacent to an
eyepiece of the viewing optics with an adapter.
In one embodiment, the second housing or base is not separable from the main
body by
the end-user. In one embodiment, the second housing or base is not
interchangeable with
multiple or other viewing optics.
In one embodiment, the disclosure relates to a system comprising a viewing
optic having
a main body with a first optical system and a base coupled to the main body
and having a second
optical system, such as an integrated display system, and a laser rangefinder
device.
1. Integrated Display System
In one embodiment, the second housing comprises an integrated display system.
In
another embodiment, a base comprises an integrated display system. In yet
another embodiment,
the base having an integrated display system is coupled to a main body of a
riflescope. In still
another embodiment, the base is coupled to a bottom portion of a main body of
a riflescope.
In one embodiment, the base has an integrated display system comprising an
active
display, collector optics, and a reflective material, including but not
limited to a mirror. In one
embodiment, the integrated display system has the following architecture: an
active display,
followed by collector optics, followed by a reflective material such as a
mirror.
FIG. 12 depicts a top cut-away view of the base 220 that couples to a main
body of a
viewing optic. The base 220 comprises an integrated display system having a
micro display
1210, collector optics 1220, and a mirror 1230. In one embodiment, the mirror
1230 can be
positioned at any suitable angle.
52
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
FIG. 13 depicts a side cut-away view of a base 220 with an integrated display
system
having a micro display 1210, collector optics 1220, and a mirror 1230. A main
body 210 has a
beam combiner 320 located above the mirror 1230.
FIG. 14 depicts a side cut-away view of riflescope with a main body 210 and a
separable
base 220. The base 220 comprises a micro display 1210, collector optics 1220,
and a mirror
1230. The mirror 1230 is positioned at about 45 degrees. The scope body 210
has a beam
combiner 320 that is located approximately above the angled mirror 1230. The
beam combiner
320 is located approximately below the elevation adjustment knob 1410 of the
scope body 210.
The active display 1210 is located in the base on the ocular assembly side
1420 when the base
220 is coupled to the main body 210 of the viewing optic.
As depicted in FIG. 15, the images generated from the micro display 1210 can
be
redirected from the display optical axis A onto the viewing optical axis A
through a mirror 1230
to a beam combiner 320 in the main body 210 for simultaneously superimposing
or overlaying
into the first focal plane 1510 the digital images onto the images of the
scene viewed by the
viewer through the optics. Because the beam combiner 320 is positioned before
the first focal
plane 1510, and the combined image is focused on the first focal plane, the
displayed image and
the viewed image do not move in relation to one another. This is a major
advancement
compared to devices that inject the image into the second focal plane.
In one embodiment, as shown in FIG. 16, the active display 1210 is located in
a portion
of the base closest to the objective assembly 214 as compared to the ocular
assembly of the main
body of a riflescope, when the base is coupled to the main body of a
riflescope. The main body
of the riflescope has an analog reticle 1610.
FIG. 17 depicts the riflescope 200 with a main body 210 with a beam combiner
320 and a
base 220 coupled to the main body and having an integrated display system. As
shown in FIG.
17, the active display 1210 is located in a portion of the base closest to the
ocular assembly as
compared to the objective assembly of the main body of a riflescope, when the
base is coupled to
the main body of a riflescope. By superimposing the image from the integrated
display system
onto the first focal plane, the user is still able to use a traditional glass
etched reticle 1610 for
aiming purposes.
In one embodiment, the integrated display system can direct generated images
from the
active display along a display optical axis A. The generated images can be
directed from the
53
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
display optical axis A to a mirror in the base to a beam combiner in a main
body of a riflescope
for simultaneously superimposing or overlaying the generated images onto the
images of the
scene viewed by the viewer through an optics system of the main body, wherein
the combined
image is injected into or focused onto the first focal plane of the optic
system of the main body.
In one embodiment, the image generated from the active display in the base is
focused on
the first focal plane of the main body of a riflescope, which allows the
display generated images
to maintain alignment with externally mounted accessories.
In one embodiment, the image generated from the active display in the base is
focused on
the first focal plane of the main body of a riflescope, thus, the generated
image is not tied to the
movement of the erector tube. The generated image is independent of movement
of the erector
tube.
In one embodiment, light from an active micro-display is collected by a group
of optical
lenses. The light from the display is reflected to a beam combiner in the
riflescope main tube
assembly and an image of the display is formed that is coincident with the
first focal plane of the
riflescope. This image of the display is combined with the image coming from
the scene (target)
and is perceived as being "underneath" the traditional wire or glass etched
reticle. In one
embodiment, the "traditional" reticle, which is still utilized, occludes both
the image of the scene
and the image of the display. If the luminance of the display is increased to
sufficient brightness
levels, the image of the OLED display will saturate the image of the scene and
will appear to
occlude the scene as well.
In yet another embodiment, the integrated display system in the base can
direct generated
images along a display optical axis "B," onto viewing optical axis A in the
main body of a
riflescope. The images can be redirected from the display optical axis B with
a mirror or similar
reflective material in the base to a beam combiner in the main body onto the
viewing optical axis
A in the main body, which allows for simultaneously superimposing or
overlaying the generated
images onto the images of the scene viewed by the viewer through the optics of
the main body.
The generated images from the active display in the base are directed toward a
mirror, which
reflects the images to a beam combiner.
In one embodiment, display optical axis "B" and viewing optical axis "A" are
substantially parallel, although other embodiments may be differently oriented
as desired.

port. In still another
embodiment, numerous input sources can be input to the microcontroller and
displayed on the
active display.
In one embodiment, an active display and a beam combiner are not located in
the same
housing. In one embodiment, an active display and a beam combiner are located
in separate
housings.
In one embodiment, the active display can be a reflective, transmissive or an
emissive
micro-display including but not limited to a micro display, transmissive
active matrix LCD
display (AMLCD), Organic light-emitting diode (OLED) display, Light-Emitting
Diode (LED)
display, e-ink display, a plasma display, a segment display, an
electroluminescent display, a
surface-conduction electron-emitter display, a quantum dot display, etc.
In one embodiment, the LED array is a micro-pixelated LED array and the LED
elements
are micro-pixelated LEDs (also referred to as micro-LEDs or LEDs in the
description) having a
small pixel size generally less than 75 m. In some embodiments, the LED
elements may each
have a pixel size ranging from approximately 8 m to approximately 25 m, and
have a pixel
pitch (both vertically and horizontally on the micro-LED array) ranging from
approximately 10
m to approximately 30 m. In one embodiment, the micro-LED elements have a
uniform pixel
size of approximately 14 m (e.g., all micro-LED elements are the same size
within a small
tolerance) and are arranged in the micro-LED array with a uniform pixel pitch
of approximately
25 m. In some embodiments, the LED elements may each have a pixel size of 25
m or less
and a pixel pitch of approximately 30 m or less.
In some embodiments, the micro-LEDs may be inorganic and based on gallium
nitride
light emitting diodes (GaN LEDs). The micro-LED arrays (comprising numerous
LEDs
arranged in a grid or other array) may provide a high-density, emissive micro-
display that is not
based on external switching or filtering systems. In some embodiments, the GaN-
based, micro-
LED array may be grown on, bonded on, or otherwise formed on a transparent
sapphire
substrate.
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the sapphire substrate is textured, etched, or otherwise
patterned to
increase the internal quantum efficiency and light extraction efficiency
(i.e., to extract more light
from the surface of the micro-LEDs) of the micro-LEDs. In other embodiments,
silver
nanoparticles may be deposited/dispersed on the patterned sapphire substrate
to coat the substrate
prior to bonding the micro-LEDs to further improve the light efficiency and
output power of the
GaN-based micro-LEDs and of the micro-LED array.
In one embodiment, the active display can be monochrome or can provide full
color, and
in some embodiments, can provide multi-color. In other embodiments, other
suitable designs or
types of displays can be employed. The active display can be driven by
electronics. In one
embodiment, the electronics can provide display functions, or can receive such
functions from
another device in communication therewith.
In one embodiment, the active display can be part of a backlight/display
assembly,
module or arrangement, having a backlight assembly including a backlight
illumination or light
source, device, apparatus or member, such as an LED backlight for illuminating
the active
display with light. in some embodiments, the backlight source can be a large
area LED and can
include a first or an integrated lens for collecting and directing generated
light to a second,
illumination or condenser lens, for collecting, concentrating and directing
the light onto active
display, along display optical axis B, with good spatial and angular
uniformity. The backlight
assembly and the active display are able to provide images with sufficient
high brightness
luminance to be simultaneously viewed with a very high brightness real world
view through
optics, while being at low power.
The backlight color can be selected to be any monochrome color, or can be
white to
support a full color microdispl ay. Other backlight design elements can be
included, such as other
light sources, waveguides, diffusers, micro-optics, polarizers, 'birefringent
components, optical
coatings and reflectors for optimizing performance of the backlight, and which
are compatible
with the overall size requirements of the active display, and the luminance,
power and contrast
needs.
FIGS. 16 and 17 depict representative examples of an integrated display system
in a base
that couples to a main body, showing a display, an optics system, and a
mirror. The integrated
system functions with an optics system housed in a main body of a viewing
optic, which is
depicted above the integrated display system.
56
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
Representative examples of micro displays that can be used include but are not
limited to:
Microoled, including MDP01 (series) DPYM, MDP02, and MDP05; Emagin such as the
SVGA,
micro-displays with pixel pitches are 9.9x9.9 micron and 7.8x7.8 micron, and
Lightning Oled
Microdisplay, such as those produced by Kopin Corporation. Micro LED displays
can also be
used including but not limited to those produced by VueReal and Lumiode.
In one embodiment, the electronics working with the active display can include
the
ability to generate display symbols, format output for the display, and
include battery
information, power conditioning circuitry, video interface, serial interface
and control features.
Other features can be included for additional or different functionality of
the display overlay
unit. The electronics can provide display functions, or can receive such
functions from another
device in communication therewith.
In one embodiment, the active display can generate images including but not
limited to
text, alpha-numeric, graphics, symbols, and/or video imagery, icons, etc.,
including active target
reticles, range measurements and wind information, GPS and compass
information, firearm
inclination information, target finding, recognition and identification (ID)
information, and/or
external sensor information (sensor video and/or graphics), or images for
situational awareness,
for viewing through the eyepiece along with the images of the view seen
through optics. The
direct viewing optics can include or maintain an etched reticle and bore
sight, and retain high
resolution.
In one embodiment, the utilization of an active display allows for a
programmable
electronic aiming point to be displayed at any location in the field of view.
This location could
be determined by the user (as in the case of a rifle that fires both
supersonic and subsonic ammo
and thus has two different trajectories and "zeros"), or could be calculated
based upon
information received from a ballistic calculator. This would provide a "drop
compensated"
aiming point for long range shooting that could be updated on a shot to shot
interval.
In one embodiment, the active display can be oriented to achieve maximum
vertical
compensation. In one embodiment, the active display is positioned to be taller
than it is wide.
In one embodiment, the active display is oriented as shown in FIG. 18, which
allows for
the maximized range of vertical adjustment 1810 of an active reticle within a
riflescope.
Maximized vertical adjustment is beneficial since it allows for the ballistic
compensation of
scenarios at longer range.

CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the integrated display system further comprises a processor
in
electronic communication with the active display.
In another embodiment, the integrated display system may include memory, at
least one
sensor, and/or an electronic communication device in electronic communication
with the
processor.
In one embodiment, the disclosure relates to a viewing optic having a main
body with an
optics system for generating images of an outward scene and a main body beam
combiner that is
placed in line with the optics system, and a base coupled to the main body
with an integrated
display system having a first active display for generating images, and a
second active display
perpendicular to the first active display, wherein the generated images from
either the first active
display or the second active display are projected into a first focal plane of
the optics system
providing simultaneous viewing of the generated images and images of the
outward scene when
looking through an eyepiece of the scope body.
In one embodiment, the disclosure relates to a viewing optic having a main
body with an
optics system for generating images of an outward scene and a main body beam
combiner that is
placed in line with the optics system, and a base coupled to the main body
with an integrated
display system having a first active display for generating image, a second
active display for
generating an image, a base beam combiner configured to combine the first
image and the
second image, and a reflective material for directing the combined image to
the main body beam
combiner for simultaneous overlaid viewing of the combined image and the image
of an outward
scene in a first focal plane when looking through an eyepiece of the scope
body.
In one embodiment, a base beam combiner is located to the right of the first
display. In
yet another embodiment, a second active display can be placed into the system
perpendicular to
the primary active display. This allows both displays to be used and projected
onto the focal
plane of the viewing optic individually or even simultaneously.
Method of Use for Range Finding
In one embodiment, the active display can display range measurements obtained
from a
laser rangefinder. In one embodiment, a LRF can be coupled to a viewing optic.
In one
embodiment, the LRF is directly coupled to the outer scope body of the
riflescope. In another
embodiment, a portion of a LRF is directly coupled to the outer portion of the
scope body of the
riflescope.
58
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the LRF is indirectly coupled to the outer scope body of
the
riflescope. In another embodiment, a portion of a LRF is indirectly coupled to
the outer portion
of the scope body of the riflescope.
In yet another embodiment, a LRF is not coupled to the riflescope but
communicates with
the riflescope via either hard-wiring or wirelessly.
In general operation, a LRF provides a pulse of laser light that is projected
into the scene
via the projection optics. This laser light illuminates the object, and a
portion of the laser light is
reflected back toward the LRF. Part of the reflected laser light returning to
the device is captured
by the receiving optical system, and is directed to a detector. The device
includes a timer
starting when the laser light pulse is transmitted and stopping when the
returning laser light is
detected. A calculator portion of the device uses the elapsed time from
transmission of the laser
light pulse until detection of the returning reflected laser light to
calculate the distance to the
object.
In one embodiment, distance calculations are transmitted to the active
display, and the
generated images (distance measurements or calculations) are redirected from
the display optical
axis "B" onto the viewing optical axis A with a mirror and a beam combiner for
simultaneously
superimposing or overlaying the images (distance measurements or calculations)
onto the
images of the scene viewed by the viewer through the viewing optics.
Windage Range Bar
In another embodiment, the active display can generate a windage range. In one
embodiment, a user can supply a range of wind values, and software can
generate windage data,
for example a windage range variance bar. In one embodiment, the windage data
is transmitted
to the active display, and the generated images, e.g., windage range variance
bar, is redirected
from the display optical axis "B" onto the viewing optical axis "A" with a
mirror and a beam
combiner for simultaneously superimposing or overlaying the images (windage
range variance
bar) onto the images of the scene viewed by the viewer through the viewing
optics.
In one embodiment, the windage data includes the minimum wind hold point to
the
maximum wind hold point.
In one embodiment, the windage data is transmitted to the active display, and
the active
display can generate a digital reticle into the field of view at the
appropriate wind hold.

WO 2020/101768 PCT/US2019/045493
In one embodiment, the active display can generate a color display to convey
an extra
level of information to the user in a quick-to-comprehend format. In one
embodiment, the
active display can generate a series of color coded symbols to indicate a
readiness to fire.
In one embodiment, the active display can generate a series of color coded
symbols to
color code objects in the target scene. In one embodiment, the active display
can color code
friendly forces from enemy forces. In another embodiment, the active display
can color code
targets of interest.
In one embodiment, the active display can generate a series of color coded
symbols to
indicate status of windage adjustment. In one embodiment, a red dot can
indicate that windage
adjustment has not been completed while a green symbol could indicate that
windage adjustment
has been completed.
In another embodiment, the active display can generate an aiming point with
color. In
one embodiment, the aiming point would be a red color if proper adjustments,
including but not
limited to windage, range, and elevation, have not been performed. In another
embodiment, the
aiming point would be a yellow color if some but not all shooting adjustments
have been
completed. In still another embodiment, the aiming point would be green if all
the requisite
shooting adjustments have been completed, and the aiming point is fully
compensated.
In yet another embodiment, flashing and steady states of symbols may be
utilized to
convey similar status information regarding the adjustment of the aiming
point.
In still another embodiment, the active display can generate text that is
shown in colors to
indicate status. In one embodiment, red text can indicate that in input
parameter has not been
entered or calculated, and green for text indicating a parameter which has
been input or
calculated.
Markers for Impact Zone in Range Finding
In one embodiment, an active display can generate circles, squares, or other
shapes to
allow the user to quickly encompass or encircle the impact zone of a
projectile.
Hold-over Estimation and Compensation
In another embodiment, the active display can generate an aiming point
compensated for
a moving target based on user input for the direction and rate of movement.
For example, the
user may input a rate of movement of 5 miles per hour to the left. This would
be added to the
windage value if the wind and movement are in the same direction, and
subtracted from the
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
windage value if the wind and movement are in opposite direction. Then, when
the aiming point
and/or windage value bar are plotted on the display, the aiming point will
include the proper
amount of hold-over to allow the user to place the aiming point dot on the
desired impact zone
and take the shot, rather than to have to place the aiming point ahead of the
moving target to
compensate for movement.
Team Operation via Camera and Remote Display Manipulation
In one embodiment, the active display in conjunction with a network interface
allow for
an additional level of enhanced operation and usage. In one embodiment, the
reticle images of a
plurality of shooters over a network can be viewed. Each shooter's reticle
camera image is
shown on one or more consoles, and network processes and interfaces enable a
group-level of
coordination, training, and cooperation not before available in individual
riflescopes.
Training and Coaching. In a training or coaching scenario, the coach can see
how each
shooter has aligned his or her reticle on his or her respective target. By
being able to actually see
the reticle alignment, the coach or trainer can then provide instructions on
adjustments and
repositioning, such as by verbal instructions (e.g. by radio or in person).
In another embodiment, the coach's console can be provided with a pointing
means, such
as a mouse or joystick, for which control data is transferred from the console
to the rifle's
integrated display system via the network. This coach's mouse or joystick then
controls an
additional dot or pointer in the display of the scope of each shooter, which
allows the coach to
visually show the shooter which target to use, which range marker bar to use,
and where to
position the reticle relative to the target. In one embodiment, each shooter
can be provided with
his or her own coach's dot so that the coach may provide individualized
instruction to each
shooter.
Fire Coordination. In another embodiment, the active display can be used in
the
coordination and implementation of a multi-shooter fire team. In one
embodiment, the
commander of the team operates a coach's console and uses the coach's dots to
assist in assigning
targets to each shooter, communicating changes in reticle placement, etc.
Snapshots for Remote Review and Approval. In another embodiment, the active
display and network processes can allow the shooter, provided with a control
means, to take a
"snapshot" of his or her reticle view. This snapshot of the user's reticle
view can include an
image of a target of question. When the image is received by the commander or
coach, the
61
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
commander or coach review the image and approve or disapprove taking the shot.
For example,
in a coaching scenario, the user may take a snapshot of an animal he or she
believes is a legal
animal (age, species, gender, etc.) to take. If the coach agrees, the coach
can so indicate by
positioning or moving the coach's dot in the shooter's reticle.
Biometric Classification of Target. In another embodiment, the snapshot of the
reticle
image is received by a biometric recognition and/or classification process,
such as a facial
recognition system. The biometric recognition and/or classification process
may be onboard the
gun, such as being integrated into the display control logic, or may be remote
to the gun
interconnected via the network. The results of the recognition and/or
classification process may
be provided in the reticle by transmitting the results via the network to the
control logic, and
updating the display appropriately.
Side-by-Side Image Display. In another embodiment, an image is downloaded to
the
integrated display system via the network, and is displayed coincidentally in
the reticle with the
viewed images of target. A downloaded image can be used to make a side-by-side
comparison
by the user of the currently viewed target with a previously-taken image or
photo of a target
similar to that which the shooter is instructed or desiring to take. For
example, during doe
season, a new shooter may be provided an image of a deer doe for reference in
the reticle, which
can be compared in real time to the actual animal being viewed through the
scope. In a military
or law enforcement application, an image of a sought enemy or fugitive can be
displayed in the
reticle for real-time comparison by a sniper to face of a person being viewed
through the scope.

CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In another embodiment, the integration of the 530nm ¨ 570nm digital display
1910
allows for relatively higher efficacy than any other color display, due to the
sensitivity of the
human eye. This allows for a smaller amount of power consumption, relative to
powering a red
or blue display to the same photometric brightness.
In yet another embodiment, the integration of the 530nm ¨ 570nm digital
display 1910
gives the end user greater ability to discern digital overlays from the
background created by the
ambient light in a day sight.
b. AMOLED
In one embodiment, the disclosure relates to an integrated display system that
includes an
AMOLED micro display.
FIG. 21 depicts an integrated display system with a AMOLED digital display
2110.
FIG. 22 is a schematic of exemplary images 2210 that can be displayed with an
AMOLED digital display. As shown in FIG. 22, a glass etched reticle 2010 can
be used with the
apparatuses and systems disclosed herein. These images are examples only, and
should not be
construed to limit the amount or type of information that can be displayed
with an active display.
In one embodiment, the AMOLED 2110 generated image is
integrated/imaged/focused in
the first focal plane. In one embodiment, the use of an AMOLED display 2110
allows for
increased contrast and greater complexity within data displayed into a
riflescope.
In one embodiment, the integration of the AMOLED display 2110 allows for the
selection of individual pixels to be illuminated, giving the ability for
complex data configurations
to be displayed with ease in the riflescope.
In another embodiment, the integration of the AMOLED display 2110 allows for a
small,
lightweight package size inside the riflescope, due to the decreased need for
back lighting in the
system.
In another embodiment, the integrated display system does not require a
backlight display
assembly.
In yet another embodiment, the integration of the AMOLED display 2110 allows
for
decreased power consumption, as the ability to optimize power usage to
individual pixels is now
available.
In one embodiment, the integration of the AMOLED display 2110 gives a contrast
ratio,
which allows for a clean "heads up" style display within the scope. The
contrast ratio allows
63
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
each floating feature to be individually targeted and represented without a
low glow around the
pixels.
B. Collector Lens System
In one embodiment, integrated display system has an optical system based upon
the use
of optical lenses as a part of one or more lens cells, which include the lens
itself and a lens cell
body to which the lens is mounted. In one embodiment, the lens cell includes a
precision formed
body that is generally cylindrical or disc shaped. This body has a central
aperture for mounting
the lens in alignment with an optical axis of a larger optical system. The
cell body can also be
said to have its own alignment axis, which will ultimately be aligned with the
optical axis for the
larger system when the lens cell is mounted therein. In addition, the lens
cell serves as a
"holder" for the lens, serves as a mechanism by which the lens can be mounted
to and in the
larger optical system, and (finally) serves as a means by which the lens can
be manipulated by
and for the purposes of that system.
In one embodiment, the integrated display system comprises a collector lens
system, also
referred to as a lens system. In one embodiment, the collector lens system
comprises an inner
lens cell and an outer lens cell.
FIG. 23 is a representative example of a collector lens system 2310, which has
an inner
lens cell 2315 and an outer lens cell 2320. In one embodiment, an outer lens
cell 2320 contains
at least one lens and an inner lens cell 2315 contains at least one lens. In
one embodiment, the
inner lens cell 2315 rotates on the inside surface of the outer lens cell
2320. As shown in FIG.
23, an active display 1210 is coupled to a flat machined surface at the back
of the inner lens cell
2315. In one embodiment, the active display 1210 can be directly coupled to
the inner lens cell
2315. In yet another embodiment, the active display 1210 can be indirectly
coupled to the inner
lens cell 2315.
One advantage of the collector optics system disclosed herein is that the
inner lens cell
being combined with the micro display mount provides a solid rotational
mechanical axis to
position the vertical axis of the micro display.
FIG. 24 is a representative depiction of a base 220 that couples to a main
body of a
viewing optic, wherein the base has a collector optics system 2310 as part of
an integrated
display system. In FIG. 24, the main body is depicted by the beam combiner 320
and the
viewing optic reticle 2420.
64
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
The outer lens cell 2320 is fixed in place in relation to the viewing optic
system in the
main body while the inner lens cell 2315 is allowed to rotationally float
inside of the outer lens
cell 2320. By placing pressure against a surface 2410 of the inner lens cell
2315 that is located
below the axis of rotation of the lens cell, the vertical axis of an active
display 1210 can be
aligned with the vertical axis of the reticle 1610 of the viewing optic
system.
FIG. 25 is a representative depiction of one embodiment for aligning the tilt
of the
vertical axis of the active display with the vertical axis of the reticle. As
shown in FIG. 25,
opposing set screws 2505 can be tightened against a surface of the inner lens
cell 2315 that is
located below the axis of rotation of the lens cell. The set screws 2505 can
be used to align the
vertical axis of the micro display 1210 with the vertical axis of a reticle in
the optical system in a
main body of a viewing optic. The rotation of the inner lens cell 2315 can be
retained by
tightening set screws 2505 securely against the lower surface of the inner
lens cell 2315, thereby,
rotationally locking the vertical axis of the micro display 1210 in place.
FIG. 26 is a representative depiction of a rear cut-away view of the collector
lens system
2300 with a micro display 1210 or active display tilt adjustment mechanism.
When a micro
display is injected into the optical system of a viewing optic through the use
of beam combiners
or wave guides, an additional method of compensation is needed in order to
eliminate tilt error
between the reticle's vertical axis and the injected image of the micro
display's vertical axis. Set
screws 2505 can be tightened against a surface of the inner lens cell 2315
that is located below
the axis of rotation of the lens cell, thereby aligning the vertical axis of
the micro display 1210
with the vertical axis of a reticle in the optical system in a main body of a
viewing optic.
FIG. 27 is a representative depiction of a method and apparatus for
eliminating parallax
between a micro display and the reticle in an optical system in the main body
of a viewing optic.
An outer lens cell 2320 contains at least one lens on the right hand side of
FIG. 27 and an inner
lens cell 2315 contains at least one lens on the left hand side of FIG. 27.
The inner lens cell 2315
slides along the optical axis on the inside surface of the outer lens cell
2320. A micro display
1210 is coupled to the inner lens cell 2315. A spring 2710 is installed
between the outer lens cell
2320 and the inner lens cell 2315 to cause the cells to separate when not
under a compression
force.
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
FIG. 28A is a representative depiction of a base, which has the collector
optics system
2300, coupled to a main body of a viewing optic. In FIG. 28A, the main body is
depicted by the
beam combiner 320 and the viewing optical reticle 2810.
The outer lens cell 2320 is fixed in place in relation to the viewing optic
and the inner
lens cell 2315 is allowed to float inside of the outer lens cell 2320. By
forcing the inner lens cell
2315 forward by use of a screw or a wedge 2820 that places force on the back
of the inner lens
cell/active display mount, the axial position of the image is changed so that
the focal plane of the
micro display image lies on the same plane as the viewing optic reticle in the
main body of the
viewing optic. Thus, parallax between the micro display and the reticle is
eliminated.
The position of the inner lens cell is kept in place through the action of the
spring
pressing outwards against the screw or wedge. Parallax between the active
display and the
reticle can be eliminated without changing the amount of light that is
collected from the active
display and without degrading the image quality of the system.
By implementing the use of the spring between the inner and outer lens cell
and the force
on the back of the inner lens cell/micro display, the maximum amount of light
can be collected
from the micro display and provides a rapid, simple, and accurate method of
adjustment.
In one embodiment, the inner lens cell 2315 and the outer lens cell 2320 can
comprise
two or more lenses. In yet another embodiment, the lens system can comprise 3,
4, 5, 6, 7, 8, 9,
or greater than 10 lenses. Lens can be obtained from a variety of commercial
manufacturers
including but not limited to LaCroix Optics (www.lacroixoptics.com) and
Diverse Optics
(www.diverseoptics.com). In one embodiment, the inner lens cell and the outer
lens cell
comprise a collector lens system.
In one embodiment, the lens system is composed of a five (5) lens system. In
one
embodiment, the five lens system is comprised of 5 singlet lenses. In another
embodiment, the
five lens system is comprised of two doublet lenses and a singlet lens. In yet
another
embodiment, the five lens system is comprised of 3 singlet lenses and 1
doublet lens. In one
embodiment, at least one plastic aspheric is used as a first element.
In one embodiment, the lens system is a five lens system with the following
order: an
aspheric singlet closest to the active display, followed by a singlet lens,
followed by a doublet
lens, followed by the final singlet lens.
66
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the lens system is a five lens system with the following
order: an
aspheric singlet closest to the active display, followed by a singlet lens,
followed by a singlet
lens, followed by a doublet lens.
In one embodiment, the lens system is a five lens system having the following
configuration: lens 1 closes to the active display is 11 mm in diameter and
9.3 mm thick; lens 2
is 9 mm in diameter and 1.9 mm thick, the doublet has one lens (lens 3) that
is 13.5 mm in
diameter and 2.1 mm thick, and another lens (lens 4) that is 13.5 mm in
diameter and 4.1 mm
thick, and lens 5 that is 13.5 mm in diameter and 3.3mm thick.
In one embodiment, the air space between one lens to the next lens ranges from
about 1
mm to about 20 mm. In one embodiment, the air space between one lens to a
subsequent lens
ranges from about 5 mm to about 20 mm. In one embodiment, the air space
between one lens to
a subsequent lens ranges from about 10 mm to about 20 mm.
In one embodiment, the distance between the active display and the first lens
is
minimized in order to collect the maximum amount of light from the display. In
one
embodiment, the distance between the active display and the first lens is less
than 2 mm. In
another embodiment, the distance between the active display and the first lens
is selected from
the group consisting of: less than 1.8 mm, less than 1.5 mm, less than 1.3 mm,
less than 1.1 mm,
less than 0.9 mm, less than 0.7 mm, less than 0.5 mm, and less than 0.3 mm.
In one embodiment, a five lens system is housed in an inner lens cell and an
outer lens
cell. In one embodiment, the inner lens cell is constructed by installing an
asphere into the inner
lens cell from the opposite end of where the display seat is; followed by a
spacer; followed by
lens 2, which can be a 9mm singlet; followed by a lock ring, which holds both
lenses in place.
In one embodiment, the outer lens cell is constructed by inserting lens 5,
which can be the
13.5 mm singlet into the outer lens cell from the display end of the cell;
followed by a spacer;
followed by the doublet, which can be lens 3 and 4, followed by a lock ring.
FIG. 28B is a representative depiction of a base, which has the collector
optics system or
collector lens system. The inner lens cell 2315 is constructed by installing
an asphere 2840 into
the inner lens cell from the opposite end of where the display seat is;
followed by a spacer;
followed by a glass meniscus 2850. In one embodiment, the glass meniscus can
be lens 2 as
described above. The outer lens cell 2320 can be constructed by inserting a
glass doublet 2860
followed by a glass singlet 2870.
67
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the collector lens system comprises a five lens system
comprising
2840, 2850, 2860, and 2870, with 2840 being closest to the active display, and
2870 being
farthest from the active display. In one embodiment, the inner lens cell 2315
comprises 2840
and 2850. In one embodiment, the outer lens cell 2320 comprises 2860 and 2870.
In one embodiment, the spacing between lens 2 in the inner cell and lens 3 in
the outer
cell is changed when the inner lens cell moves axially along the inner
diameter of the outer lens
cell. This causes the focal plane of the image of the display to shift and is
used to null out
parallax between the projected display image and the passive reticle in the
main body of the
viewing optic.
In one embodiment, the focusing of the display image onto the first focal
plane of the
optic system in the main body is accomplished by changing the air spacing
between lens 2 and
lens 3, of a 5-lens system, which is accomplished by varying the position of
the inner lens cell
with respect to the outer lens cell.
In one embodiment, lens assemblies may also be assembled together within a
lens barrel,
which is an integral mechanical structure holding a series of lenses. It is
used to position the
lenses axially and radially with respect to each other, and to provide a means
of interfacing the
lens assembly with the system of which it is a part. Lens elements are
radially positioned by the
inside diameter or ID of the barrel wall. The outside diameter or OD of the
lens elements are
ground to fit ID of the barrel wall. The axial position of the lens elements
is accomplished by
cutting lens seats during assembly. The lens elements can then be constrained
on the seats by
epoxy, retaining rings, etc.
C. Reflective Material
In one embodiment, the integrated display system comprises a reflective
material 1230.
In one embodiment, the reflective material 1230 is a mirror. In one
embodiment, the integrated
display system comprises one or more mirrors. In one embodiment, the
integrated display system
comprises two, three, four or more mirrors.
In one embodiment, the mirror is positioned at an angle from 30 to 60 , or
from 30 to
55 , 30 to 50 , or from 30 to 45 , or from 30 to 40 , or from 30 to 35
relative to the emitted
light of the display.
68
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the mirror is positioned at an angle from 30 to 60 , or
from 35 to
60 , 40 to 60 , or from 45 to 60 , or from 50 to 60 , or from 55 to 60
relative to the emitted
iight of the display.
In one embodiment, the mirror is positioned at an angle of at least 40 . In
one
embodiment, the mirror is positioned at an angle of 45 relative to the
emitted light of the
display.
In one embodiment, and as shown in FIG. 29, the tilt of a mirror 2910 along
the vertical
axis is able to be adjusted by use of a screw or similar mechanism. By turning
a screw in against
the base or rear of the mirror 2910, the angle at which the image of the micro
display is reflected
into the beam combiner can be changed. This correspondingly changes the tilt
of the focal plane
at the viewing optic's reticle 2930 of the optical system in the main body of
a viewing optic.
Using this adjustment, parallax error can be eliminated between the micro
display and the reticle
along the vertical axis.
In one embodiment, the mirror is fastened to the base with one or more screws.
In one
embodiment, the mirror is fastened to the base using a chemical compound such
as an epoxy, a
resin, or a glue or combinations thereof.
In one embodiment, the position of the mirror can be adjusted in relation to
the beam
combiner to eliminate any errors, including but not limited to parallax error.
In one embodiment, the position of the mirror can be adjusted in relation to
the active
display to eliminate any errors, including but not limited to parallax error.
2. Power System
In one embodiment, the base that couples to the main body of the viewing optic
has a
power system. In another embodiment, the base of a viewing optic has a cavity.
A battery
cavity can be integrated into the base that couples to the main body of a
viewing optic.
FIG. 30 is a representative schematic of a base 220 with a battery compartment
3005,
wherein the base 220 is coupled to the main body 210 of a riflescope 3000. As
shown in FIGS.
30 and 31, the battery cavity 3005 extends from each side of the base to
encase a battery,
including but not limited to a CR123 battery. The CR123 battery has increased
power capacity
and discharge as compared to smaller batteries or coin style batteries.
69
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the battery cavity 3005 is integral to the base 220 so that
only the
battery cap is needed to protect the battery from the environment. No
additional sealing is
required.
In one embodiment, the battery cavity 3005 in the base 220 is located closer
to the
objective assembly 3010 of the main body 210 of a viewing optic as compared to
the ocular
assembly.
In one embodiment, the battery cavity 3005 in the base 220 is located closer
to the ocular
assembly of the main body 210 of a viewing optic as compared to the objective
assembly.
FIG. 32 is a representative depiction of the battery compartment 3005
integrated into the
base 220. In one embodiment, the cavity 3005 is designed to have the positive
side of the battery
inserted first with a mechanical stop at the bottom of the battery cavity to
prevent improper
installation and operation of the battery.
In one embodiment, the integrated battery cavity 3005 can use the same gasket
as the
base 220 uses to the main body 210 of the riflescope. This provides a more
reliable seal and
eliminates a mechanical device as a separate battery cavity is not required.
Secondly, there is no
mechanical device securing the battery cavity since it is integrated into the
base. This reduces
the need for any mechanical interface for securing the battery compartment.
Because there is no
need for mechanical locking of the battery cavity, the integrated battery
compartment reduces the
points of failure for a traditional battery compartment.
The integrated battery compartment eliminates any obstacles that are in the
way of the
user. The integrated battery compartment is located under the viewing optic
out of the way of
any of the adjustments and knobs found on traditional viewing optics. The
integrated battery
cavity is a significant advancement as it allows the necessary space to
accommodate a larger
battery.
In one embodiment, the viewing optic can be set-up in a manner to minimize
battery
drain and to maximize battery life. For example, the viewing optic with a
laser rangefinder is
activated when an operator presses a button or switch. A range finder
designator is displayed on
the screen. An external range finder's output laser will coincide with the
designator through an
initial calibration step when zeroing the viewing optic. When the external
rangefinder is
activated by the operator, information is sent to the viewing optic wirelessly
or via the
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
communication port signaling the device that information has been received and
needs to be
displayed.
If the viewing optic is turned on and no data is received from an external
device, the
viewing optic will power down after a user set time. After displaying received
information from
an external device, the power down timer is started and will power down the
device if no further
button presses are registered.
If more information is received from an external device, the screen will be
cleared of the
prior information and the updated information will be displayed and the power
down timer will
be started. This cycle can continue as many times as the operator chooses.
During the time when information is displayed on the screen, a cant indicator
is displayed
on the screen. This is refreshed from an accelerometer communicating with the
microcontroller
on a time interval. When the microcontroller is in sleep mode, the integral
buttons on the
viewing optic will control the brightness of LEDS illuminating a glass etched
reticle. When the
viewing optic is operating, control of these LEDS becomes suspended and the
brightness of the
screen will be altered during the corresponding buttons presses.
3. Picatinny Mount
In one embodiment, the disclosure relates to a viewing optic having a main
body and a
base with a battery compartment and a picatinny mount that can couple to the
battery
compartment. In one embodiment, a removable picatinny mount is attached to a
protruded
battery compartment that is incorporated into a base coupled to a main body of
a riflescope.
FIGS. 33-35 are representative schematics of a riflescope with a main body 210
and a
base 220 coupled to the main body 210, with the base having a battery
compartment 3005 that
can attach to a picatinny mount 3305. In one embodiment, the picatinny mount
3305 is aligned
with the battery compartment 3005 and secured with fasteners.
By attaching the mount 3305 to the battery compartment 3005 of the base 220,
it utilizes
the material needed to make the cavity 3005 for the battery. This eliminates
the need for any
additional material from the base, thereby making the viewing optic lighter
and less invasive.
In one embodiment, the mount is located towards the objective of the turrets
and parallax
knob so as to not intrude on the user's ability to adjust the riflescope.
Further, the top ring is
removable allowing for easy attachment of an accessory device, such as a laser
rangefinder. By
71
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
utilizing the picatinny mount disclosed herein, no additional structural
support from the top
portion of the ring is needed since the integrated base secures the
riflescope.
In one embodiment, the mount incorporates a cantilevered picatinny rail that
extends
forward towards the objective of the riflescope. This allows a weapons mounted
laser range
finder to sit directly over the bell of the riflescope. This style of mount
allows for decreased shift
of impact and increased accuracy of the ranging device. It decreases the
potential for shift of
impact since there are fewer variables that may affect the ranging device from
acquiring the
desired target.
4. Data Ports
In one embodiment, the disclosure relates to a viewing optic with a main body
and a base
with an active micro display for generating an image and combining the
generated image into the
image of the scene in the First Focal Plane of the main body of the viewing
optic, wherein he
base has axially orientated data ports for interfacing with ancillary devices
including but not
limited to remote control switches and laser range-finders.
FIG. 36 is a representative schematic of a riflescope 3600 with a main body
210 and a
base 220 with axially oriented data ports 3605. In one embodiment, the viewing
optic can have
one axially oriented data port. In another embodiment, the viewing optic can
have two or more
axially oriented data ports.
By utilizing an axially oriented data port 3605, the top down profile of the
overall
viewing optic is minimized, thereby increasing the robustness of the mounted
system and its
connections.
5. External Video Sources
In one embodiment, the active display in the base can be used as the optical
train or
optical system of a clip on device, including but not limited to a thermal
imaging system and a
night vision system.
Thermal imaging systems allow for various waves of the electromagnetic
spectrum to be
imaged and relayed to the user, which typically cannot be captured by the
human eye.
Traditional thermal weapon sights are composed of two systems paired together:
an infrared
optical system, which views the scene and a visible wavelength optical system
consisting of a
micro display and lenses to recreate the image in front of the riflescope.
There are also instances
of catalytic photon enhancement, creating what us known as "night vision"
systems. However,
72
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
clip-on devices are typically attached to the rifle rail in front of the main
body of the riflescope.
This setup blocks all of the ambient light typically imaged by the scope, and
allows for use of the
digital image only. In order to switch back to the traditional image, the user
must remove the
system from the rail. This can cause an impact shift due to the alignment
setup that you go
through each time the sight is changed. These clip-on units also tend to be
large, due to the need
for an eyepiece/imaging system behind the digital display in the units. In
traditional systems,
any live video feed would be a completely digital image, including the visible
spectrum output.
FIG. 37 is a representative schematic of a riflescope 3700 with a main body
210 and a
base 220 with an active display 1210 and collector optics 1220 that can be
used as the optical
system of a thermal imaging unit 3705. The active display 1210 generates an
image that is
focused on a first focal plane of the main body of the scope, using a beam
combiner to integrate
the image into the traditional day optic. The integration of the digital
display allows for the user
to overlay the digital image onto the ambient day optic. With the digital
display disclosed
herein, the clip-on unit does not have to be removed from the front of the
viewing optic to view
the ambient day optic. Rather, the digital display can be turned on and off as
needed.
The integration of the digital display allows for zero image shift when
switching between
day visible and digital optic. Since the system is fully integrated, there is
no need to zero each
time the digital optic is turned on. The system is synchronous, due to the
alignment of the
combiner optical system.
In one embodiment, the integration of the digital display makes up the optical
train that
would typically be the rear half of a clip-on unit. Because there is already a
micro display in the
base of the viewing optic, the thermal sight would only need the infrared
optics; the image
created by the thermal sensor can be transmitted to the active display, which
is already
incorporated into the base of the viewing optic. By integrating a thermal or
NV sight in this
manner, the thermal/NV device will be much shorter and lighter than current
weapon sights on
the market. This allows for the design of smaller lighter systems, since half
of the optical train is
now integrated directly into the base that couples to the main body of a
viewing optic. There is
no need for a rear optical system or display to be integrated into the clip-on
unit that contains the
sensing device.
Additionally, if the thermal weapon sight were to be mounted off to the side
of the
riflescope so that the thermal optics did not occlude the riflescope
objective, then it would be
73
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
possible to overlay a thermal image overtop of the visible image that the user
would be viewing.
This would have the benefit of being able to highlight humans, animals, or
anything with a heat
signature that stands out in an otherwise neutral daylight scene.
In one embodiment, the integration of the digital display disclosed herein
creates the
advantage of having live video feed into the focal plan of a viewing optic,
without interruption of
the day visible sight.
In one embodiment, the integration of the digital display allows for seamless
integration
of imaging overlays, such as live thermal imaging view, and hyperspectral
overlay systems. The
visible image is now analog, rather than another digital display.
In one embodiment, the integration of the digital display disclosed herein
creates the
advantage of continued image feed, even if power were to suddenly drain on the
digital system.
A true analog image would still be available, which would not be the case in
traditional digital
output systems.
In one embodiment, the integration of the digital display allows for multiple
types of
imaging systems to be mounted separate from the front of the viewing optic. A
thermal imaging
system can be aligned to the bottom or side of the viewing optic and still
feed that image directly
onto a focal plane within the main body of the viewing optic.
6. EMI Permeable Window
In one embodiment, the main body, the base or both the main body and the base
of a
viewing optic can have a window that is sealed with a material transparent to
the electromagnetic
waves used for the wireless communication. Transparent materials include but
are not limited to
plastics, resins or epoxies.
In one embodiment, the window allows EM waves to propagate from the
communicating
device with reduced interaction from the metallic body of the viewing optic.
This increases the
rate at which data can be transmitted. It also allows the wireless
communication device to
operate at a lower power level due to reduced signal losses.
III. Additional Sensors/Devices
In another embodiment, the disclosure relates to a viewing optic with a main
body and a
base with an integrated display system and one or more sensors. In one
embodiment, the sensors
include but are not limited to a Global Positioning System, accelerometers, a
magnetometer,
MEMS rate sensors, tilt sensors, laser rangefinder.
74
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
A. Pointing Angie, Target Location, and Communication
In one embodiment, the viewing optic can have inertial MEMS Rate Sensors to
determine
the pointing angle of the weapon in inertial space. Example products are the
LCG-50 by Systron
Donner and the SiRRS01 by Silicon Sensing. In another embodiment,
accelerometers can be
incorporated into the embedded electronics to determine absolute tilt angle of
the viewing optic
and track weapon accelerations due to general movement or a firing event.
To support targeting, in various embodiments, the viewing optic can have a GPS
and/or
digital compass. In one embodiment, the GPS and/or digital compass can be
integrated into the
viewing optic, for example, as board level modules. In another embodiment, the
GPS and/or
digital compass can be associated with a separate device that communicates
with the viewing
optic.
Several manufacturers offer custom of the shelf modules for GPS and digital
compass
functionality that are small form factor and have low power consumption
characteristics. These
devices are designed to be integrated into embedded components. For example,
Ocean Server
Technology makes a 054000-T compass with 0.5 deg. accuracy and has a power
consumption
under 30 ma and is less than 3/4" square. An example of a GPS device is the
DeLorme GP52058-
Module that is 16 mmx16 mm and is available in a surface mount package
offering 2 meter
accuracy.
In one embodiment, the viewing optic can have a data interface that provides
one or both
of wired and wireless capabilities designed to interface to systems such as
the BAE Personal
Network Node and the emerging SIM radio. These interfaces provide various
communications
capabilities, such as range, sensor, and other tactical data (e.g. anti-
fratricide detector,
environmental sensors, etc.). This unique functionality is used in various
embodiments to obtain
and communicate environmental, target, and situational awareness information
to the community
of interest. Generally speaking, the various embodiments are designed to
enable the war fighter
to quickly acquire, reacquire, process, and otherwise integrate data from a
variety of passive and
active sources into a ballistic firing solution thereby increasing the
shooter's effectiveness.
In another embodiment, the sensors provide information to the active display
in order to
generate real time position data of different targets onto the first focal
plane of the main body of
the viewing optic. In another embodiment, the sensors are part of an external
device that
communicates with the integrated display system.
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
By using these sensors in the viewing optic, or on an external device that is
rigidly
connected to the viewing optic, or on a weapon that the viewing optic is
mounted to, the exact
position of the viewing optic can be obtained, as well as the exact direction
that the viewing optic
is pointed, and external targets can be calculated in relation to the viewing
optic position and
aimed direction.
As the user moves the viewing optic around or as targets move in relation to
the viewing
optic, the position of the targets would be updated continuously and in real
time by the sensors
communicating with the integrated display system, so that by viewing through
the viewing optic
the user would be able to see where the targets are in relation to where they
are looking.
This approach has strong utility in military applications where you may have
personnel in
different locations that are trying to communicate a specific target location
to one another. For
example, with Close Air Support (CAS), a pilot may be flying an aircraft and a
unit on the
ground may be relying on the aircraft to drop a bomb on a target. Often times,
it is difficult for
the unit on the ground to relay to the aircraft the exact location of the
target. The process of
relaying the target information between the ground unit and the aircraft is
often referred to as
"talking on to the target," and involves communicating what the unit or
aircraft is seeing in their
field of view, such as what landmarks might be visible near the target and so
on.
This process often takes quite a bit of time and can cause confusion because
things often
look different from the air than they do on the ground. It is critical that
each unit be sure that
they are all looking at the same target, because if the aircraft mistakes the
target they may drop a
bomb on friendly units, or non-combatants.
By allowing location and position sensors to communicate with the active
reticle display
of the integrated display system, these issues are solved. The user of the
viewing optic can
designate a target in their scope, the scope knows the GPS location of the
scope, the exact
direction it is pointing and distance to the target and can calculate the
exact GPS coordinate of
the target. This information can be fed into a universal system, such as Link
16, that all friendly
units are connected to. Now the aircraft can simply look at a display in their
aircraft and the new
target is displayed on their map as soon as another unit designates it.
This makes finding targets much quicker and the confirmation that both units
are looking
at the same target much easier. Accuracy is extremely important in determining
target locations,
thus, the active display generated images need to be displayed in the first
focal plane of the main
76
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
body of the viewing optic. If the generated image from the active display were
put into the
second focal plane of the viewing optic, then the target locations would only
be accurate when
the viewing optic reticle was at its "zeroed" location. If the user of the
viewing optic had dialed
anything on their turrets, for example to engage a long range target, then all
of the target
information in the display would be shifted the amount dialed in the turrets
and not be accurate.
By using this with the active display images injected into the first focal
plane, the
displayed data is agnostic of any adjustments made to the reticle position and
is automatically
compensated for. This means that target data in the field of view is always
accurate.
B. Environmental Sensors
In one embodiment, the viewing optic can have one or more pressure, humidity,
and/or
temperature sensors designed to collect and use environmental data for
ballistic correction
purposes. The sensors are available in miniature configurations suitable for
integration into the
viewing optic. An example of a miniature, low power, water proof, barometric
pressure sensor is
the MS5540 from Interseina. This component measures 6.2x6.4 mm,
In one embodiment, the sensors can be coupled to the main tube of the viewing
optic or
to the base of the viewing optic,
C. Uphill and Downhill
In one embodiment, the viewing optic can have a z-axis accelerometer that can
be used to
measure tilt angle of the scope with respect to vertical. This tilt angle can
be integrated into a
ballistic solution at the time of target selection. Once the target is
selected, the system may be
able to automatically integrate actual uphill or down tilt into the ballistic
solution and display the
solution into the first focal plane of the viewing optic so that the digital
reticle or corrected
aiming point is displayed correctly. This can provide for a very fast and
effective means of
aiming in long range uphill or downhill engagements.
IV. Viewing Optic with Display System and Laser Range Finder
In one embodiment, the disclosure relates to a viewing optic having a main
body and a
base with an integrated display system, and a laser rangefinder. In one
embodiment, the laser
rangefinder is coupled to the viewing optic. In another embodiment, the laser
rangefinder is
independent from the viewing optic and communicates with the viewing optic,
either wirelessly
or through a cable.
77
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the laser rangefinder couples to the viewing optic via a
mounting rail
that attaches to the base through the battery compartment.
In one embodiment, a laser rangefinder can be used to determine distance to
target.. In
various embodiments, the laser transmits in the near IR for covertness. A
typical wavelength
used for laser rangefinder devices operating in the near infrared (NW) is 905
nm.
In one embodiment, the specific laser power and spectral characteristics are
selected to
meet range and eye safety requirements of the viewing optic. The rangefinder
is of sufficient
power to produce accurate measurements out to, illustratively, 1500 meters,
2500 meters or
whatever effective range is associated with the firearm or weapon intended to
be used with the
viewing optic. For rangefinder operation, in some embodiments a single button
control is
dedicated for making or executing a rangefinder measurement.
:In one embodiment, the range to target may be communicated to the active
display that
generates an image of the range to target and superimposes the range to target
onto the first focal
plane of a viewing optic when viewing the target scene.
In one embodiment, the viewing optic has a computing device with ballistics
calculator
capabilities. In one embodiment, the main body of the viewing optic has a
computing device
with ballistics calculator capabilities.
In one embodiment, a laser rangefinder can be used to measure a target
distance,
calculate projectile ballistics and communicate the corrected aim point to an
active display in an
integrated display system, which then superimposes the image of the corrected
aim point onto
the first focal plane of a viewing optic with a reticle attached to a moveable
erector lens system.
Importantly, because the active display generated image is combined with the
image from
the target in front of the first focal plane and then focused onto the first
focal plane, the target
image and display image never move in relation to one another. Therefore, any
aiming reference
created by the digital display will always be accurate, regardless of how the
moveable erector
system is adjusted.
When an external laser range finder feeds range information to the riflescope,
an aiming
reference or laser designator will need to be created by the digital display
in order for the user to
know where in the field of view the LRF is aiming in order to accurately hit
the correct target
with the laser. The digital display image and the target image of the
objective lens system in the
main body of the riflescope do not move in relation to one another. Therefore,
the digital laser
78
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
designator will accurately show the user the correct location of the LRF laser
point of aim, no
matter how the turrets have been adjusted to move the moveable erector lens
system.
On the other hand, if the digital display image was integrated into the optic
system
anywhere behind the first focal plane then when the turrets are adjusted, and
the erector lens
system is moved/tilted, then the image of the digital display would move in
relation to the target
image and the digital LRF designator would move in relation to the actual
laser point of aim.
This could lead to an incorrect range measurement if the user dials any
elevation or windage
adjustment into the turrets and forgets to dial back to the original position
the turrets were set to
when the user aligned the digital reticle with the actual laser point of aim.
In addition, when a traditional riflescope is zeroed to the rifle, the user
will typically
select a "zero" range, often times 100 yards, that is used align the
riflescope reticle with the point
of impact of the rifle projectile. This is usually accomplished by adjusting
the turrets of the
riflescope, and thus the angle of tilt of the erector lens system, in order to
align the reticle with
the point of impact of the projectile. After the initial "zero" of the
riflescope has been set, the
turrets allow the user to further make adjustments to the riflescope reticle
position in order to
compensate for targets at different ranges or for changing wind drift
variables that affect where
the point of impact of the projectile may change from the initial "zero"
position.
If the digital display were to be integrated into the riflescope system behind
the first focal
plane then the ballistically calculated correction factor to the point of aim
would have the
potential to be incorrect if the user had made any adjustments to the turrets
from the initial
"zero." For example, if a ballistic calculator determined that the correction
required 10
milliradians of elevation adjustment to hit the target, the digital display
would place an aim point
milliradians below the center of the crosshair. However, if the user had
dialed 5 milliradians
into the elevation turret from the initial "zero" position, the digital aim
point would actually be
aiming 15 milliradians below the initial "zero."
By injecting the digital display into the first focal plane of the optic
system of the main
body of a riflescope, it allows the digital display to be totally unaffected
by any change in the
turret adjustment or position of the erector system. This means that in the
example above, the
digital aim point would actually appear only 5 milliradians below the center
of the reticle, for a
total of, the correct, 10 milliradian ballistic drop (user had previously
dialed 5 milliradians into
the elevation turret from the initial "zero" position). In short, injecting
the digital display image
79
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
into the first focal plane of the optic system of the main body renders the
digital display image
completely agnostic to any change in the turret position and thus the erector
lens system
movement/tilt, which provides the needed accuracy.
In one embodiment, the laser range finder capability provides dynamically
defined
ballistic solutions based upon data acquired. The range to target may be used
by the on-board
computer when processing tracer trajectory to determine the best point along
the measured
trajectory- path to use for determining the ballistic correction for the next
shot.
In one embodiment, the laser rangefinder is integrated into the scope and has
a dedicated
outgoing laser transmission port. In one embodiment, the optical path of this
dedicated laser axis
is positioned in the corner of the housing so it is unobstructed by the main
objective lens. The
detection path for the incoming reflected laser signal is through the main
objective of the scope
where the light is directed to a photo detector by a near IR beamsplitter.
This arrangement takes
advantage of the relatively large aperture of the main objective lens to
increase the signal to
noise of the measurement.
FIGS. 38 through 44 provides photographs of a viewing optic 3800 having a main
body
3810 with an optical system and a base 3820 coupled to the main body 3810
having an
integrated display system, with a laser range finder 3830 coupled to the top
of the main body
3810. The viewing optic 3800 can have two auxiliary ports 3805 for
communication with an
external source. The viewing optic 3800 can have a picatinny mount 3305 that
couples to the
outside of a battery cap for a battery cavity 3005 in the base 3820.
FIGS. 45 through 46 provide depictions of a viewing optic 4500 having a main
body
4510 with an optical system and abase 4520 coupled to the main body 4510
having an
integrated display system, with a laser range finder 4530 coupled to the top
of the main body
4510. The viewing optic 4500 can have a single auxiliary port 4535 for
communication with the
laser range finder 4530.
FIGS. 47 and 48 provide depictions of a viewing optic 4700 having a main body
4710
with an optical system and a base 4720 coupled to the main body 4710 having an
integrated
display system. In certain embodiments, the viewing optic 4700 can have a
picatinny mount
4730. In certain embodiments, the viewing optic can have an auxiliary port
4735.
V. Additional Embodiments
1. Digital Zeroing
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the disclosure relates to method for using a digital
reticle for
alignment and zeroing purposes. In one embodiment, the viewing optic has a
physical reticle and
a digital reticle, with the physical reticle being connected to the erector
system. The user
"zeros" the physical reticle by using turrets to move the reticle and erector
system so that the
center of the reticle coincides with the bullet point of impact.
After the physical reticle is zeroed, the digital reticle must also be zeroed.
Since the
digital reticle is formed by an active or digital display that is fixed in
position, the only way to
zero or align the digital reticle is by using a digital means. The digital
reticle position can be
moved by the user so that the center of the digital reticle coincides with the
center of the physical
reticle.
In another embodiment, digital zeroing can also be used with a laser
designator. When
used in conjunction with an external laser range finder, the viewing optic
laser designator must
be aligned with the direction that the laser range finder is pointing. Most
external laser
rangefinders have a visible laser and an infrared laser. The infrared laser is
the laser that actually
measures the range. The visible laser can be turned on an off and coincides
with the aim of the
infrared laser. The visible laser allows the user to see where the laser is
aiming. Once the visible
laser is turned on, the user can then digitally adjust the laser designator to
coincide with the point
of aim of the visible laser. Then the visible laser can be turned off and the
user can use the laser
designator in the viewing optic display to ensure accurate aiming of the laser
rangefinder.
2. Holographic Waveguide
In one embodiment, the disclosure relates to a viewing optic having a main
body with a
first optical system and a base with active display and a holographic
waveguide. In one
embodiment, the integration of the holographic waveguide reduces the package
size and weight
of a traditional beam combining system. The integration of the holographic
waveguide can
increase the overall transmitted brightness ratio, such that a greater
percentage of each optic
system light gets to the end user.
FIG. 49 is a representative depiction of a viewing optic 4900 with an optical
system in a
main body 4910 and a base 49 having an active display 1210 and a holographic
waveguide
system 4925. The holographic waveguide system 4925 spans the main body 4910 as
well as the
base 4920. A digital or active display 1210 generates an image to the
collimation optic 4930,
which sends the image to the in-coming hologram waveguide 4926. The image
exits the
81
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
waveguide via the output hologram 4927 and the image is injected into the
first focal plane 4930
of the optical system 4940.
In one embodiment, the integration of the holographic waveguide reduces the
need in
specialized coatings made for beam combiners. In addition, the integration of
the holographic
waveguide disrupts the need for a mirror system, alleviating the need for
complex mechanical
alignment systems.
The integration of the holographic waveguide allows you to create a copy of
the complex
optical system needed to image a display, eliminating the need for a complex
system to be put
into every system.
The integration of the holographic waveguide allows for the use of LCOS, LCD
and
OLED systems to display information within an optical system. The nature of
the system allows
for various types of illumination systems in conjunction with the different
types of displays used
within the system.
The use of a holographic waveguide allows for the implementation of non-static
illuminated reticles. The reticles can be changed just as images on a screen
are changed. The
holographic waveguide allows for daylight bright reticle systems without the
need for traditional
illumination methods.
The integration of the holographic waveguide creates the ability to create a
non-static
holographic sight. The out coupling hologram can send light as defined by the
master optical
system, allowing for changes in the sight picture of a holographic sight.
The integration of a holographic waveguide can be used with any monochromatic
or
polychromatic light source. The use of complex multiplexed Bragg gratings
allow for the
integration of multi-chromatic illumination systems.
3. Tracking Bullet Trajectory
One of the difficulties associated with long range engagements is the ability
to determine
the accuracy of an initial shot so that a timely correction can be made to
improve the accuracy of
the next shot. A traditional technique used to determine the round's point of
impact is to attempt
to detect bullet trace and/or actual splash point of bullet. This can be
difficult in many long range
engagements. In the case of a sniper team, the follow up shots also require
feedback from the
spotter to get the pertinent data back to the shooter. This can take several
seconds using only
verbal communications.
82
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the viewing optic can have an imaging sensor adapted to
detect
image frames associated with a bullet flight path and communicate said image
frames to a
computing device, which can then calculate bullet trajectory therefrom.
In one embodiment, the viewing optic with a main body and a base with an
integrated
display system can allow tracer rounds to be detected by on-board image
processing capabilities
so as to determine the bullet's trajectory just before it impacts the target
area. In one
embodiment, this data can be communicated back into a ballistics computer
thereby quickly and
efficiently creating a follow up firing solution for the second round, which
can be communicated
to the active display and the corrected aiming point superimposed into the
first focal plane of the
main body of the viewing optic.
Automating the feedback loop with trajectory and splash point detection by
computer and
combining this to the active display and superimposing an electronic aiming
point correction in
the first focal plane advantageously decreases the total time required to make
an accurate second
shot. This time reduction can be at a critical point in the engagement
process. After the first shot
is made, the window of opportunity to make a second shot can quickly narrow,
especially if
delays extend past the point in time when the sonic boom of the initial shot
reaches the intended
target.
Environmental conditions and windage drifts can have substantial impact on the
ballistic
trajectory of the round over large distances. For instance a M193 bullet can
drift about 4 feet in a
modest 10 mph crosswind at 500 yards. Windage effects become even more
exaggerated at
greater distances since the speed of the bullet decreases as the range and
total time of flight
increases.
A variety of tracer round options are available. A standard tracer is used
conventionally
by the shooter to see the trajectory of the bullets in-flig,ht path. A tracer
round can emit light in
the visible or IR spectrum depending on the composition of the tracer
material. The latter is
effective when the shooter is using night vision equipment. In addition some
tracers can emit
light dimly at first and then brighten as the round travels downrange, A fuse
element can control
-when the tracer lights up after firing of the round in order to delay
igniting the tracer material
until the bullet is well downrange. The fuse delay mitigates the risk of the
tracer revealing the
shooter's firing location.
83
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, a viewing optic with an integrated display system can use
tracer
rounds to detect, determine and/or display a bullet's trajectory just before
it impacts the target
area. In one embodiment, covert tracers that have long delay fuses and emit in
the near FR region
(700 nm to 1000 nm) of the electromagnetic spectrum can be used. Light emitted
in the near IR
region is invisible to the human eye, but can be detected by an imaging sensor
using
conventional glass optics. A tracer round of this type can be particularly
effective in maintaining
the shooter's covertness for Sniper operations while providing a significant
automated bullet
tracking capability for accurately determining next shot correction
requirements. Thus, various
embodiments are adapted to cooperate with one or more types of tracer rounds
to implement the
functions described herein.
Since the imaging sensor in the daylight embodiment is also sensitive to
visible light, a
standard daylight tracer can also be used for bullet tracking. In both the
visible and near IR cases,
the tracer rounds can take advantage of having long delay fuses to increase
covertness as the
system only needs to detect the bullet's flight in the final moments before
impact.
In one embodiment, a camera associated with a viewing optic can record the
trajectory of
the bullet and using the suite of sensors embedded into the viewing optic, it
can calculate the
exact geo-positional trajectory of the bullet, as well as the bullet's point
of impact.
In another embodiment, the viewing optic may also use a stabilized camera to
compensate for recoil from the firearm. The viewing optic would accurately
track the movement
of the stabilized camera, and compensate for that movement to accurately
calculate the geo-
positional trajectory of the bullet. This embodiment would allow the shooter
to track their own
trajectory and compensate for any misses more accurately.
In both embodiments, the geo-positional trajectory of the bullet could then be
shared to
other users who also active displays in devices they are using, such as
another riflescope,
spotting scope, or goggles using a microdisplay or holographic technology to
display the
trajectory into their field of view.
In one embodiment, the tracking of the bullet's trajectory incorporates
capturing video
frame images of the glowing tracer bullet in flight. The spatial location of
the bullet in selected
image frames is extracted through image processing techniques and then
correlated with data.
from other video frames to establish the bullet's trajectory.
84
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
Image frames are selected for processing based on correlation with the firing
event. When
the round is fired from the weapon, the time of muzzle exit is immediately
determined by
processing accelerometer data obtained from an on-board weapon axis
accelerometer included in
various embodiments. A correlation window from the time of muzzle exit is then
started where
various embodiments begin frame by frame processing of video images to
identify therein a
small cluster of pixels associated with the tracer round at a particular X-Y
position in space. The
frame images may be taken with an exposure time that is optimized to capture
the bullet as it
transmits a small number of individual pixels in the X-Y frame. Since the
frame rate of the
camera and time of muzzle exit is known, the bullet's distance from the weapon
in each frame
can be established using the known flight characteristic of the bullet. This
data is contained in
the onboard tables pertinent to each weapon and its associated rounds or,
alternatively, received
from a tactical network communication with the weapon sight.
If an absolute range to target is known from a laser rangefinder measurement,
the
position of the round at the target range can be calculated by determining the
point in the
trajectory that corresponds to the target range. The elegance of this
technique is that the
measurement is done from in-flight data and does not rely on bullet impact
with a physical
surface. The position calculated would correspond to an angular elevation and
azimuth relative to
the weapon's position and can be used to determine the ballistic pointing
correction needed for
increased accuracy. As part of this next shot ballistic correction
calculation, various
embodiments use inertial pointing angle data to calculate the relative
reference point between
inertial pointing angle of the gun at muzzle exit and the pointing angle at
the time of splash. This
allows the calculation to take into account any angular movement of the gun
that occurred during
the bullet's time of flight to target range.

collector optics 5110,
and a mirror 5115. The integrated display system is oriented such the display
5115 and the
collector optics 5110 are perpendicular with the beam combiner 5025. In FIG.
51, the active
display 5105 is closer to the ocular system as compared to the objective
system of the viewing
optic.
FIG. 52 depicts an alternative embodiment of a viewing optic 5000 having a
scope body
5005 and a compartment or notch 5010 on the top of the scope body 5005. The
compartment
5010 has an integrated display system comprising an active display 5105,

optics with a
beam combiner 5025 in the scope body 5005 for simultaneously superimposing or
overlaying the
generated images and the viewed images, wherein the combined image is injected
into the first
focal plane. Because the beam combiner 5025 is positioned before the first
focal plane, and the
combined image is focused on the first focal plane, the displayed image and
the viewed image do
not move in relation to one another. This is a major advancement compared to
devices that inject
the image into the second focal plane.
In yet another alternative embodiment, the viewing optic has a scope body and
a

V. Viewing Optic with Advanced Reticle Features
A. Active Display Pattern based on Magnification Setting
In one embodiment, the disclosure relates to a viewing optic having a main
body and a
base with an integrated display system, wherein the active display of the
integrated display
system generates multiple reticle patterns that are projected into the first
focal plane of the field
of view.
In one embodiment, the disclosure relates to a viewing optic having a main
body and a
base with an integrated display system, wherein an active display of the
integrated display
system generates a reticle pattern based on magnification level.
In one embodiment, the disclosure relates to a viewing optic having a main
body with one
or more sensors that can track or monitor the magnification level of the optic
and a base with an
integrated display system, wherein an active display of the integrated display
system generates a
reticle pattern based on magnification level. Depending on the magnification
level, the active
display system can generate different reticle patterns that are optimized for
different optical
magnification levels. In one embodiment, the active display of the integrated
display system can
automatically switch between reticle patterns based on the magnificent level.
In one embodiment, the viewing optic with an integrated display system can
project
digital features or aim points that are optimized for the specific
magnification setting being used.
In one embodiment, the main body of the viewing optic has a sensor associated
with a
magnification adjustment mechanism of the sighting device to produce a signal
indicative of an
adjustment of the optical magnification of the viewing optic. The viewing
optic further includes
an electronic controller in communication with the sensor and the active
display of the integrated
display system. The electronic controller in response to the signal produced
by the sensor,
87
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
communicates to the active display to generate a reticle pattern, which is
viewable through an
eyepiece in a field of view thereof superimposed upon an image of a distant
object.
:In some earbodi in ents, the electronic controller and active display are
configured to
produce a first reticle pattern, such as a close-quarters reticle pattern, in
response to the signal
indicating a first magnification setting; and, in response to the signal
indicating a second
magnification setting greater than the first magnification setting, the
electronic controller and
active display may produce a second reticle pattern that is distinct from the
first reticle pattern.
For example, the second reticle pattern may he a long-range reticle pattern,
such as a sniper
reticle.
In some embodiments, the sensor may include an electro-mechanical or optical
digital
encoder (which may be rotational or linear), a potentiometer, a combination of
one or more
magnets and one or more hall effect sensors, or other suitable device operable
for sensing the
position or movement of the magnification adjustment mechanism and producing a
corresponding electrical signal. In one embodiment, the sensor and described
in :FIGS. 69 and
70,
In one embodiment, the active display is not in the main body of the viewing
optic.
In one embodiment, one or more reticle patterns can be selected from including
but not
limited to 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20,
and greater than 20. In
one embodiment, the viewing optic with an integrated display system can chose
between at least
10, or at least 20, or at least 30, or at least 40 or at least 50 reticle
patterns.
In one embodiment, the active display of the integrated display system
projects reticle
patterns into the first focal plane of the field of view that are based on
specific magnification
settings. Upon a change in magnification setting, the reticle pattern
generated from the active
display switches so that the aim point is immediately useful for the operator.
The switching of
the reticle can be based on the magnification setting.
As way of example, and not to be limited, at a 1X magnification setting, the
active
display can generate a small center dot that is projected into the first focal
plane. Upon a
magnification change to 8X, the active display generates a cross hair pattern
with long range
hold over dots that are projected into the first focal plane. The sensor
determines a change in
magnification, which is communicated to a controller, which changes the
reticle pattern of the
active display.
88
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the viewing optic with an integrated display system
projects
information and aim points that are designed to aid the operator in engaging
targets at short and
long ranges. In one embodiment, multiple "pages" of information or reticle
patterns can be
designed and loaded into the system and different pages can be displayed
depending upon the
magnification setting.
In one embodiment, the reticle pattern from the active display is projected
onto an etched
reticle of the first focal plane. Projecting the digital reticle onto an
etched or fixed reticle
provides necessary protection in the event of a system failure.
FIG. 53 is a representative depiction of a Close Quarter Battle reticle 5300
at 1X
magnification. The thick arched lines 5305, the primary horizontal line 5307,
the primary
vertical line 5309, numbers and arrows are components of an etched reticle.
The center dot 5310
is generated from an active display of an integrated display system. This type
of reticle is used
for close quarter battle; the center dot represents a fast target acquisition
aim point.
FIG. 54 is a schematic representation of the reticle from FIG. 53 but with the
magnification setting of the viewing optic at 8x. As can be seen, the center
dot 5310 being
projected from the active display has become obtrusively large under 8X
magnification.
FIG. 55 is a representaive depiction of a reticle pattern 5500 that provides
useful
informatioin when the viewing optic is set at a magnification setting of 8X.
The thick arched
lines 5502, the primary horizontal line 5504, the primary vertical line 5506,
numbers and arrows
represent the etched reticle. The center aim point 5510, the 6 ballistically
compensated windage
dots 5520, and the square in the upper left 5530, which represents a
rangefinder designator
displaying a hypothetical range to target are components generated by the
active display.
FIG. 56 is a representative depecition of the rectile pattern 5500 at a low
magnificaiton
setting.
With references to FIGS. 53-56, when the optical magnification setting is at
1X, the
reticle pattern 5300 includes etched reticle features 53052 5307, and 5309 as
well as a first set of
multiple marks 5310 (such as a circle and/or an aiming dot) generated from the
active display
and projected onto the first focal plane reticle. Preferably, the red dc
pattern 5300 formed at least
in part by the first set of marks 5310, is a type of close-quarters reticle
(COB reticle.) having
minimal marks to provide a less cluttered viewable area, such as illustrated
in FIG. 53.
89
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
When the optical magnification setting is increased, an electronic controller
and the
active display (in response to a signal received from a sensor, including but
not limited to the
sensor described in FIGS. 69 and 70) replacelaiter/change the first reticle
pattern with a second
set of multiple marks, which form (at least in part) a second reticle pattern
5500 that is distinct
from the first reticle pattern 5300 and which typically includes at least some
different
functionality.
For instance, the second reticle pattern may include different aiming features
and
additional marks, such as relating to estimating distance, calculating windage
and elevation
adjustments, or other suitable marks commonly used in ranging reticles such as
shown in FIG.
55.
It can be seen therefore, that creating multiple "pages" of features and
reticle patterns for
the active display, storing them in a memory system, and automatically
switching between the
reticle patter s as the operator changes magnification settings on the viewing
optic will be
extremely useful.
B. Active BDC Reticle
Ballistic Drop Compensating (BDC) reticles are designed to have hash marks
located on
the portion of the vertical cross hair that is located below the horizontal
cross hair. These hash
marks are designed at specific distances to try and closely match a specific
or set of specific
ballistic profiles.
However, the current BDC reticle designs are fixed designs. This is because
the reticles
are made using wire, metal, or etched on glass. Once the reticle is made and
installed in the
riflescope it can't be changed without taking the reticle out and installing a
new one, which can
only be practically accomplished by sending the scope back to the
manufacturer.
In one embodiment, the disclosure relates to a viewing optic having a main
body with an
optical system and a base having an integrated display system with an active
display that can
generate a BDC reticle that can be changed manually by the user at any time,
or even
automatically by the software and sensors of the viewing optic in real time.
To generate the BDC reticle for the viewing optic disclosed herein, the
riflescope can be
programmed for the specific ballistic profile of the rifle and the to be fired
cartridge. Second, the
viewing optic has sensors, as described above, such as temperature, pressure,
humidity, cant
angle, inclination angle, that can aid in giving real time updates to the BDC
reticle so that it is as
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
accurate as possible for all conditions. This allows the BDC reticle to be
custom tailored to each
rifle and the specific shooting conditions.
The BDC reticle generated in real-time by the active display allows the
shooter to have
an accurate system for shooting at various distances accurately and quickly.
As shown in FIG. 57, the reticle 5700 has standard etch and fill portions
including a
primary horizontal line 5702, a primary vertical line 5704, and numerical
markings and hash
marks along the primary and vertical crosshairs. Reticle 5700 also has
patterns and marks
generated by the active display and projected onto the first focal plane
reticle. The active display
marks in the form of a BDC reticle include the numerical markings 5710 (100-
900 on the vertical
axis in quadrants 3 and 4). As this portion is projected from the digital
display, it can be updated
in real time.
In addition to an active BDC reticle, there are times where a user/shooter
might find
themselves in a position where they are providing cover for other individuals
in an area where
targets may present themselves quickly and at varying ranges. An example might
be a sniper
who is on top of a building looking down an alley or a road that has cross
streets or doorways.
The active display can be used in conjunction with a variety of sensors
embedded into the
riflescope, such as compass, cant angle, inclination angle, GPS, etc. to be
able to accurately
determine the direction the riflescope is pointed.
Using a viewing optic having environmental sensors, an integrated display
system having
an active display for generating and projecting a BDC reticle into the first
focal plane, and a
rangefinder, a user will be able to range known landmarks, such as doors,
windows, cars, etc. and
use the controller and active display to place a range marker on those
landmarks. These range
markers are projected into the first focal plane and visible through the
viewing optic. The
environmental sensors allow the user to move the viewing optic around to view
other targets, but
the range markers would remain on the targets.
FIG. 58 is a representative image of a BDC reticle generated by the active
display and
projected onto a first focal plane reticle, with range to potential targets
indicated. A viewing
optic having a main body with environmental sensors and a base having an
integrated display
system with an active display for generating a BDC reticle will allow the user
to mark multiple
targets in one or more areas with distance indications on the target markers.
Then, if a target
were to present itself near a target marker, the user would be able to quickly
identify the range to
91
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
the target without having to range the target. The user can then employ the
active BDC reticle to
quickly hold in the correct location to engage the target.
C. Reticle Compensated for Firearm Cant
In a traditional riflescope, when shooting long range, it is important that
the firearm and
scope are level when taking a shot. When a bullet travels over a long
distance, the bullet is
affected by gravity to a degree that the shooter must take into account.
Gravity pulls the bullet
towards the ground in a consistent direction creating "bullet drop." Shooters
compensate for
this bullet drop by aiming higher than their target so that by the time the
bullet reaches the target,
it has dropped to the appropriate height, such that it hits the target.
FIG. 59 is a representative depiction of cant angle. It can be clearly seen
that the triangle
is a right triangle with the 100 angle at the top and the right angle at the
bottom. The 10
milliradian leg has become the side of the triangle that is the hypotenuse and
represents a canted
vertical section of crosshair. However, gravity is acting on the vertical leg
of the triangle.
Using trigonometry, the length of the vertical leg can be solved with the
following
equation: Cos10 = x/10 milliradians. Solving for x results in a value of 9.85
milliradians. So,
in this example, while the user/shooter may have held or dialed 10
milliradians, they only
compensated for a 9.85 milliradian shot. At long range, this is easily enough
to miss the target.
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system that uses an active display to generate a reticle that can compensates
for cant of the
firearm. The user can seamlessly shoot at distance without having to worry
about cant angle.
In a traditional riflescope the reticle is a physical cross hair that is
either metal, wire, or a
pattern that is permanently etched on glass. This means that the cant of the
reticle is always
fixed. However, with the active display technology for generating a real-time
reticle, by
overlaying a digital reticle onto the passive image, the digital reticle can
be changed at any time.
In one embodiment, the viewing optic has an internal cant sensor that can
instantly orient the
reticle generated by the active display to compensate for cant angle.
FIG. 60 is a representative depiction of a reticle 6000 with marks and
patterns oriented
for cant and generated by an active display of an integrated display system.
The primary
horizontal line 6002 and the primary vertical line 6004 are provided by the
passive or etched or
fixed reticle. The aiming point generated by the active reticle 6020
compensates for cant and is
projected or overlaid onto the passive reticle. The pivot point 6010 is at the
center of the reticle.
92
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In this case, an electronic controller/micro-controller would use the
information gathered from
cant angle and inclination angle sensors and apply software logic and
communicate with the
active display to adjust the generated image aiming point 6020 to reflect the
new zero position,
associated geometry and hold points that correspond to the orientation of the
firearm at that point
in time. The user would shoot off the digital reticle generated by the active
display, instead of
the passive or fixed reticle.
In another embodiment, the active display of the integrated display system can
generate a
digital reticle that compensates for cant, as well as for shooting at an
inclined or decline angle,
by adjusting the aim point up or down on the digital reticle. This would
eliminate the need for a
cosine indicator, which is often used to compensate for shooting in these
types of situations.
D. Digital Reticle with Wind Drift Indicators
In a traditional riflescope, reticles that have wind indicators are usually a
glass etched
reticle. Often these reticles will have a grid pattern or rows of dots to
allow the user to have a
reference point to use to aim with and compensate for wind speed. The problem
with these
reticles is that they are fixed in shape and size, since they are physically
and permanently etched
onto a piece of glass.
In one embodiment, the disclosure relates to a viewing optic having a main
body and a
base with an integrated display system having an active display for generating
a digital reticle
that uses wind drift indicators that compensate for the range to target. In
one embodiment, the
digital reticle is overlaid onto a passive reticle. By using a digital reticle
that is overlaid on a
passive reticle, the viewing optic can have a reticle that can adapt real-time
wind holds to the
ballistics, range, and environment of the specific situation.
Typically, the longer the range, the more effect a crosswind has on a bullet.
By using a
digital reticle, the wind holds can be spread out more as the distance
increases to compensate for
wind values at the specific range for the target.
FIG. 61 is a representative depiction of a reticle 6100. Multiple components
or markers
are provided by the passive reticle including the primary horizontal crosshair
6102 and the
primary vertical crosshair 6104. The active display of the integrated display
system generated
and projects a target that was ranged at 500 yards 6105 and wind holds 6110
for the specific
conditions. The end of the secondary horizontal line (across the main vertical
line) would equal a
93
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
mph wind drift, the next dot would be 10 mph, and the outer most dot would be
15 mph. The
images generated from the active display 6105 and 6110 are overlaid onto the
passive reticle.
FIG. 62 is a representative depiction of a reticle 6200. Multiple components
or markers
are provided by the passive reticle including the primary horizontal crosshair
6202 and the
primary vertical crosshair 6204. The active display of the integrated display
system generated
and projects a target that was ranged at 1000 yards 6210 and wind holds 6220
for the specific
conditions. The end of the horizontal line (across the main vertical line)
would equal a 5 mph
wind drift, the next dot would be 10 mph, and the outer most dot would be 15
mph. The images
generated from the active display 6210 and 6220 are overlaid onto the passive
reticle. It can be
seen that the secondary horizontal line 6220 extends wider, and the wind dots
are spread further
to the sides compared to the 500 yard (FIG. 61) solution to compensate for
additional wind drift
induced when the bullet travels a longer distance.
E. Reticle with Center Grid for Second Shot Correction
In the past, passive reticles have been designed to allow the shooter to have
many
reference points for shooting in varying conditions and varying ballistics.
However, since the
variety of conditions and ballistics vary so widely, these reticles have
tended to have many
features on them, such as grids of lines or dots, that cause the reticle to
appear cluttered, or busy
to the user.
In one embodiment, the disclosure relates to a reticle system comprising a
digital reticle
generated with an active display overlaid a passive reticle. The use of the
digital reticle allows
information to be shown as needed and as appropriate, which eliminates the
need for certain
information to be displayed on the passive reticle, thereby providing a
cleaner or more easily
discerned passive reticle.
In one embodiment, the disclosure relates to a viewing optic having a passive
or analog
reticle that is designed to work most efficiently in conjunction with an
active reticle. The active
reticle technology allows the viewing optic to do the complicated calculations
and display a
ballistic solution for the user. Typically, the ballistic solution will not be
in the center of the field
of view or the center of the passive reticle cross hair. This gives the user
the option to either
hold over center on the ballistic solution, or to dial the turrets until the
ballistic solution is in the
center of the field of view and in the center of the passive cross hair to
take the shot.
94
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the disclosure relates to a viewing optic with an analog
and digital
reticle that will allow the shooter to most effectively and efficiently make a
second shot
correction, while minimally obstructing their field of view like previous
passive reticles have
done, which use extensive grids of lines and dots.
FIG. 63 is a representative depiction of a wide angle view of a reticle 6300
at low
magnification. A less obtrusive row of dots is used below the horizontal cross
hair. This passive
reticle can be used as a backup, in the event the active display cannot be
generated because the
battery power or electronics of the viewing optic fail.
FIG. 64 is a representative depiction of a close-up view of the center portion
of the reticle
6400. FIG. 64 provides a view at higher magnification. This image shows a
small grid 6410
generated by the active display of the integrated display system, which is
located at the center of
the reticle. This will allow the user to make accurate measurements of first
shot impact location
to make accurate second shot corrections.
In one embodiment, the grid 6410 generated by the active display is wider than
it is tall.
This is specifically designed since calculating elevation of an impact is more
accurate than
estimating wind drift of a first shot. In this embodiment, the small plus
features of the small
grid are not illuminated but are very fine features, which allow very precise
measurement.
The active or digital reticle should get the first shot very close, therefore,
the center grid
can be much smaller than a typical passive reticle, which requires an
extensive grid that covers a
significant portion of the field of view below the horizontal cross hair.
VI. Auto Brightnesss Adjustment
As discussed throughout the application, the integrated display system allows
digial
images generated by an active display to be overlaid on top an image of an
outward scene. This
active display is injected into the image of the outward scene using
illuminated portions of the
display. For the display to be most usable it is desirable to have a high
contrast ratio between
the brightness of the passive scene and the illuminated display such that both
can be easily seen.
If the display is too dim the user will not be able to see it. If the display
is too bright the display
will overpower the passive scene.
In one embodiment, the disclosure relates to viewing optic having a main body
with an
integrated display system and a light sensor that can detect the specific
target brightness and
compensate for it.

FIG. 71 provies a representative schematic of a viewing optic 7000 with a main
body
7005 and a base coupled to the main body 7010. The main body 7005 has an
optical system for
viewing an image of an outward scene and a beam combiner 7020 with a photo
sensor 7025 and
a light filter 7030 located above the beam combiner 7020. This allows the
photo sensor to look
directly at the target scene, without creating an obstruction in the field of
view. The base 7010
has an integrated display system 7015 having an active display for generating
an image that is
projected into the first focal plane of the viewing optic.
The photo sensor 7025 and light filter 7030 generate a high contrast ratio
between the
brightness of the image of the outward scene and the generated image from the
active display.
In one embodiment, the transmission band of the filter in front of the photo
sensor can be
tuned to be narrow enough so that only the brightness of the target will be
measured and the
additional light from the display system will not be measured, which would
distort the
measurement.
VII. Viewing Optic with Auto-Ranging Capabilities
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system that incorporates the use of a camera to aid in an auto-ranging. In one
embodiment, the
disclosure relates to a system comprising a viewing optic with an integrated
display system, a
camera to aid in an auto-ranging, and a laser range finder.
In one embodiment, the disclosure relates to a viewing optic having an
integrated display
system and a camera that incorporates image recognition technology. The
systems and methods
disclosed herein greatly increase the speed of acquiring a target solution,
and eliminate the need
of a button press that may affect point of aim. In addition, the systems and
methods disclosed
herein integrate artificial intelligence into the system to determine the
quality of the ranged target
solution.
In one embodiment, the viewing optic has a camera that incorporates image
recognition
technology. In one embodiment, the camera can be attached to either the
viewing optic having an
integrated display system or a firearm and would point towards the point of
aim of the riflescope.
In one embodiment, the camera has artificial intelligence to detect a target
and
communicate with an active display of the integrated display system to
highlight the target. In
another embodiment, the artificial intelligence system can be incorporated
into the viewing optic.
96
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the artificial intelligence system can be located in the
base coupled to the
main body of the viewing optic.
In another embodiment, a thermal imaging camera lacking image recognition
technology
can be used. This would allow the thermal image to be communicated to the
active display and
overlaid onto the image of an outward scene in the viewing optic. The viewing
optic could be
programmed to only display "hot spots" of interest. For example, hot spots
that indicate human
heat, or vehicle heat, etc. Eliminating artificial intelligence will greatly
reduce the power
consumed by the system. In addition, all appropriate hot spots would appear in
the field of view
of the viewing optic, allowing the user to evaluate each one to determine if
the target was valid
or not.
After identifying a valid target, the user would simply move the viewing optic
so that the
LRF designator in the FOV was over top of the desired hot spot. Once the LRF
designator was
aligned with the hot spot, the system would automatically trigger the LRF to
take a range at that
hot spot. After taking a range, the viewing optic could either display a hold
point for the range
of the target or could simply show the range and the user could use the Active
BDC mode and
hold on the active BDC reticle for the appropriate measured range to the
target.
An additional capability to the system is that it could automatically detect
if the hot spot
remained within the LRF designator long enough to get a valid range. If not,
it would wait to
display a range until the hot spot remained within the LRF designator the
appropriate length of
time to achieve a valid target acquisition before displaying a solution. This
would eliminate the
second problem with pressing a button.
In one embodiment, the disclosure relates to the technology and method of
using an
overlaid camera image projected into the first focal plane of a viewing optic,
and using that
image in conjunction with a LRF designator to automatically range a target.
VIII. Viewing Optic with a Photosensor to Conserve Power
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system and a power saving system. In one embodiment, the power saving system
is located in a
base coupled to the main body of the viewing optic. In one embodiment, the
power saving
system comprises a proximity sensor. In one embodiment, the proximity sensor
is in
communication with a microcontroller.
97
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the power saving system can be used to place the viewing
optic in a
sleep or standby mode when a user/operator is not looking through the optic.
In one
embodiment, the systems and mechanisms can wake or activate the viewing optic
when a
user/operator is detected behind the eyepiece of the optic.
Current methods of putting the electronics to sleep or into standby are by
using a "time
out" feature, which is disadvantageous if the optic is being used for Close
Quarter Battle work
since the optic must stay on for an indeterminate amount of time as long as
there is an operator
looking through it. An accelerometer can also be used to detect motion and
thus turn the system
on. The disadvantage of that method is that if an operator is doing
observation then the gun may
have very little movement for long periods of time and thus go to sleep, even
though the operator
is still looking through the optic.
In one embodiment, the disclosure relates to a system to conserve battery
power by
turning on the viewing optic when there is an operator detected behind an
eyepiece of the optic.
In one embodiment, the power saving system can be used in any electro-optics
compatible with implementing a proximity sensor that is within a few inches of
where the
operator's face will be when using the optic.
In one embodiment, the disclosure relates to a viewing optic having a main
body and a
base coupled to the main body, wherein the base has a window in the back of
the base toward
eyepiece.
In one embodiment, the base has a proximity sensor installed into a carrier
and the carrier
is installed into the window located at the end of the base toward the
eyepiece. The proximity
sensor can communicate a signal to a microcontroller in the base or main body
when the
proximity sensor detects a reflection that is within a few inches of the
window. The distance at
which an object will activate the sensor can be adjusted either at the factory
or a software option
can be built into the user interface to allow the operator to either adjust
the sensitivity of the
sensor or disable/enable the auto sleep/standby feature.
FIG. 72 is a representative depiction of a viewing optic 7200 having a base
7205. The
base 7205 has a window 7210 located toward the eyepiece of the main body of
the viewing optic.
A proximity sensor and carrier 7215 are located in the window 7210, which is
located below the
eyepiece.

CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
FIGS. 73 and 74 are representative depictions of a viewing optic 7200 having a
base with
with a power saving system, with the viewiong optic mounted on a rifle. It can
be seen that an
operators face will be within a few inches of the back of the optic. The
sensor 7215 in the base
7205 of the viewing optic 7200 will detect a reflection from the operator's
face, thus waking the
optic up from a sleep mode. When the operator removes his/her head from the
view position, the
sensor will no longer see a reflection and will put the viewing optic into a
sleep or standby mode.
IX. Viewing Optic with Power Rail
In one embodiment, the disclosure relates to a viewing optic having a main
body and a
base with an integrated display system, wherein the viewing optic can be
powered by an external
power source that is housed in the host firearm. In one embodiment, the
viewing optic has a
main body and a base coupled to the main body, wherein electrical pins are
built into the base to
provide power from the firearm to the viewing optic. In another embodiment,
the viewing optic
can be powered by the firearm using electrical pins that are built into the
remote keypad
assembly.
In one embodimet, the dislcosre relates to methods and systems to provide
additional
power for extended periods of time to the viewing optic.
In one embodiment, the disclosure relates to a viewing optic with a main body
and a base
coupled to the main body, wherein the base has PCBs that are being used to
control a display,
sensors, and user interface of the viewing optic. In one embodiment, the base
has power input
pins that protrude through the base and contact a power pad. In one
embodiment, the power pad
is built into a Picatinny rail.
In one embodiment, the PCBs are located in a position that allows interaction
with the
input pins. In one embodiment, the pins are sealed against the base of the
riflescope to keep the
interior of the riflescope protected from the environment.
FIGS. 75 and 76 are representative depictions of a viewing optic 7500 having a
main
body and a base 7510 with power pins 7520 protruding through the base 7510 of
the viewing
optic 7500.
FIG. 77 is a representative side profile of viewing optic 7500 showing the
power pins
7520 protruding through the base 7510 of the viewing optic 7500.

CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
FIG. 78 is a representative view of the side profile of viewiong optic 7500
with the base
of the viewing optic made transparent to show the power pins 7520 which that
are attached to the
built in PCBs 7530.
In another embodiment, power supplied by the picatinny rail on the firearm
could be
delivered to the viewing optic through a remote keypad, which is used to
control the viewing
optic. In this scenario, the power pins are connected to the PCB that is in
the remote keypad and
they protrude through the built in recoil lug in the remote keypad housing.
Power is then sent
through two dedicated lines in the cable into the base of the riflescope.
FIG. 79 is a representaive image of the top of the remote keypad 7900.
FIG. 80 is a representative side profile of the remote keypad 7900 showing
power pins
8010 protruding through the built in recoil lug.
FIG. 81 is a representative bottom view of the remote keypad 7900 showing the
2 power
pins 8010 protruding out of the remote recoil lug.
FIG. 82 is a representative bottom view of the remote keypad 7900 with the
cover made
transparent to show the PCB 8205 inside of the remote body.
X. Viewing Optice with a Single Keypad with Multiple Functions
In one embodiment, the disclosrue relates to a system comprising a viewing
optic having
an integrated display system and a remote keypad system with more than one
function per
keypad button. In one embodiment, the remote keypad can control more than one
aspect of
functionality of the viewing optic, i.e. more than one function per button. In
one embodiment,
the function of the button depends on the state of either a control signal or
software bit.
In one embodiment, the disclosure relates to a remote keypad that expands the
control
that a user/operator has over a viewing optic and/or auxiliary devices that
are used with the
viewing optic.
In one embodimet, the disclosrue relates to a kepad for a viewing optic and/or
one or
more auxiliary devices that are used with the viewing optic. In one
embodiment, more than one
function is assigned to a single button of the keypad, wherein the desired
function can be
determined with a software bit or a separate mechanical switch. This can
significantly increase
the functionality of the viewing optic.
In one representative embodiment, in a first mode, a button can change the
brightness of
the display and in a second mode, the same button can activate an infrared
pointer on the system.
100
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
Using the same button for more than one function keeps the remote keypad small
and simple
with the minimal number of buttons required.
FIG. 83 is a representative depiction of a keypad with three buttons. A remote
keypad
associated with a viewing optic has 3 buttons. The top button 8305 is used to
increase the
brightness of the display, the middle button 8310 is used to fire the laser
rangefinder to range a
target and the bottom button 8315 is used to decrease the brightness of the
display. The
functionality of each button depends on the mode of operation.
In one embodiment, the keypad can have 2, 3, 4, 5, 6, 7, 8, 9, 10, or more
than 10 modes
of operation. In one embodiment, the keypad can be in communication with a
processor setting
from 10 to 50 modes of operation for the keypad. By way of example, a keypad
in
communication with a processor having 10 modes of operation for the keypad,
would provide 10
functions for each button, with the functionality determined by the mode of
operation.
Several methods can be used to change the functionality of the buttons. In one
embodiment, when a user/operator presses and holds a button on the remote for
a period of time,
the micro controller changes the function of one or more buttons. In one
embodiment, an
operator can press and hold one of the 3 buttons for a prolonged period of
time, for example, 1
second, and this will signal the micro controller inside of the viewing optic
to change a bit that
assigns new functions to the buttons. In one embodiment, pressing and holding
the top button
8305 for a period of time can set mode A, pressing and holding the middle
button 8310 for a
period of time can set mode B, and pressing and holding the bottom button 8315
for a period of
time can set mode C. Varying the time each button is engaged can activate
further modes of
operation. For example, holding button 8305 for five seconds can active mode
A, engaging
button 8305 five quick taps can active mode F.
In another embodiment, the funcionallity of the remote keypad buttons can be
changed is
through a separate mechanical switch on the viewing optic. In one embodiment,
a mechancial
switch can have 3 distinct positions, which are in communcation with 3
separate bits or programs
in the micro controller. These bits or programs can be used to assign various
functions to the
remote kepad buttons.
A representative example is shown in FIG. 84. The viewing optic has a switch
8400 in
communication with a remote keypad 8300. A first setting 8405 can assign the
top button 8305
of a remote keypad 8300 the function to increase display brightness, the
middle button 8310
101
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
could fire the laser rangefinder, and the bottom button 8315 could decrease
display brightness.
When the mechanical switch 8400 is set to a second setting 8410, the function
of the top 8305
and bottom buttons 8315 can be programmed to turn on and off auxilary pointing
lasers on the
viewing optic and the middle button 8310 can still be programmed to fire the
laser rangefinder.
When the mechanical switch 8400 is set to a third setting 8415, the functions
of the 3 buttons
could be altered again. For instance, if the viewing optic is equiped with a
digital magnetic
compass and location and landmark data was saved to the memory of a micro
controller then
information about the position of objects could be displayed inside of the
field of view of the
viewing optic (augmented reality data).
In one embodimet, the keypad is in commucantion with a processor of the
viewing optic
that allows varying modes of operation to be assigned to each button or switch
of the keypad.
For example, in one mode of operation, the buttons of the keypad have specific
functions for
marking a target of interest. The operator can use the laser rangefinder to
range a target and, use
the heading data from a digital magnetic compass to "mark" a target of
interest inside the field of
view. The buttons on the keypad could be assigned functions that are
specifically suited for this
task.
The center button on the keypad could be used to fire the laser rangefinder to
range the
target. Once the target is ranged, the top and bottom buttons could be used to
select from a
predefined list of descriptors to label the target, e.g. "landmark,"
"friendly," "hostile,"
"unknown" etc. Once the operator is done with this action, the mechanical
switch can be
changed to quickly assign functions back to the remote keypad buttons that
allow the operator to
change brightness settings, activate an infrared laser, or obtain a ballistic
solution for a target
downrange.
XII. Viewing Optic with a Relative Coordinate Mapping System
In one embodiment, the disclosure relates to technology and a method of using
a viewing
optic with an integrated display system to accurately tag and track targets
using a relative
coordinate mapping system, and/or drone technology.
Soldiers need to be able to accurately identify the location of enemy targets
and to share
that location with other soldiers, close air support, etc, and to be able to
see those targets easily
by having them overlaid into the field of view of their primary optic. The
most obvious way to
102
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
achieve this is using a combination of GPS, compass heading, altitude,
inclination, and range
finding sensors. However, there are disadvantages in relying on GPS, such as
GPS signals
require direct line of sight to the GPS satellite, which may not always be
possible. Using relative
coordinate technology and/or the use of drones, the need for GPS can be
diminished. Relative
Coordinate Technology becomes feasible when used in conjunction with a viewing
optic having
an integrated display system.
In one embodiment, a user would be able to point the viewing optic with an
integrated
display system at a landmark or target and "tag" it. If the user "tagged"
several targets, then a
relative location map could be created from the tagged targets. These tagged
targets could be
transmitted to a viewing optic of other users, who would see those tagged
targets displayed in the
field of view. All this target data would then be stored locally in one or
memory devices in the
viewing optic.
In one embodiment, the user could also use drones either as an alternative to
tagging
targets, or as a supplement to tagging targets. This would work by launching a
"cloud" of many
small or micro drones that would contain cameras and the appropriate sensors
to fly over a
battlefield and begin tagging and marking landmarks. The drones could share
that information
with each other and back to the users who would have it displayed in the
active display of their
viewing optic.
By using relative coordinate technology and/or a cloud of drones, the
disadvantages of
GPS can be overcome:
= With multiple users and multiple viewing optics, there becomes an
inherent redundancy in the stored target data. When using a cloud of drones,
that
redundancy can be increased even further. With redundancy, it becomes much
less likely
that a signal or data would be lost.
= GPS requires sending and receiving data over very long distances to and
from satellites in orbit. By using other users who are in the same battle
space, or a cloud
of drones in the same battle space, the network is much closer to the users
and target,
which increases the accuracy of the user and target coordinates.
= GPS is much easier to block, since there are a limited number of GPS
satellites. With a cloud of users and/or drones, it becomes much harder to
block all the
signals and creates more redundancy.
103
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
= Eliminating the need for a GPS module makes the viewing optic less
bulky.
XIII. Viewing Optic with Ammunition Status Indicator
When shooting in high stress scenarios, shooters can easily lose track of how
many
rounds are left in the firearm. Currently, there is no easy or convenient
method to determine the
number of rounds remaining in a firearm magazine while holding the firearm in
a firing position.
A mechanical counter may be added or integrated into the magazine, but
checking a mechanical
counter requires a shooter to look away from his sights and/or target to check
the round count.
Other current methods and systems for determining the number of rounds in a
magazine require
the shooter to lose his sight picture, physically check the magazine, or
otherwise disrupt his
stance or position.
Some magazines are clear or have clear windows to show the remaining rounds,
but the
shooter needs to break their shooting position to observe the level.
Additionally, the remaining
rounds can be obscured by a grip or receiver. In military environments, some
shooters have
loaded tracer rounds as the final rounds in a magazine to indicate that the
magazine they are
using is almost empty, but this can reveal a shooters position and requires
the use of specific
rounds.
Other methods and systems have tried to address this issue by placing a
digital read-out
on a grip, but these read-outs both project light back at the shooter and are
often placed in areas
where the shooter must break concentration from a sight picture to see the
remaining rounds.
Sometimes the read-out is an attachment to an existing firearm component,
other times the
shooter is required to replace a part, like a grip, to have the read-out
mounted on the weapon.
Some read-outs are even mounted to the bottom of a magazine, which can be
considered a
disposable or semi disposable item in some military applications, a more
expensive item.
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system that allows the user/shooter to monitor ammunition status. The
ammunition status can be
projected into a first focal plane of the optics train, and combined with the
images of the outward
scene. Proactively conducting or preparing for a magazine change better allows
the shooter to
reload at a time of their choosing rather than at a sub optimal time dictated
by an empty weapon
and magazine.
104
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the disclosure relates to the use of one or more magnets in
a
magazine, a sensor in a remote that is mounted to a weapons magazine well to
count the final
rounds in a magazine. The information is then displayed via the active display
and projected into
a first focal plane of the optics system providing simultaneous viewing of the
generated image
(round indicator/round status) and images of the outward scene when looking
through an
eyepiece of the viewing optic.
This allows the shooter to be aware of the final rounds in the magazine
without breaking
their concentration from the sight picture within the optic. Additionally, the
system adds
minimal weight as it could use largely existing hardware and would not require
substantial or
expensive modifications to the weapon or the weapon's magazine.
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system having an active display that projects the remaining rounds or a round
count into the first
focal plane of the optics train.
In one embodiment, one or more magnets can be located within a magazine
follower to
trigger one or more sensors on a weapon receiver. In one embodiment, the
magnetic sensors can
reside in a remote already connected to the viewing optic. The remote is
attached to the
magazine well of the weapon. The magazine follower rises as the rounds are
stripped or
discharged from the magazine and the magnetic sensors send information to the
active display of
the viewing optic.
This design will give the shooter feedback with regard to the number of rounds
they have
remaining in their magazine without having to break concentration from the
sight picture. In
addition, this design for ammunition tracking has limited cost and does not
increase weight of the
weapon system as the integrated display system is already present in the
viewing optic.
Additionally, sensors could reside in a remote already attached to a weapon's
magazine well.
In one embodiment, the magazine follower has one or more directional magnets
placed in
the rear of the follower so that the magnetic field is projected outside of
the magazine
perpendicular to the rounds in the magazine so the field does not interfere
with the feeding or
loading of steel cased or armor piercing steel or other magnetically affected
tips.
As rounds are fed through the magazine, the follower, and the magnets, is
raised as each
round is stripped from the magazine. One or more sensors, such as a Hall
effect sensor, are
located on the receiver of the weapon to detect the magnetic fields, the
changes in strength of the
105
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
field and the changing position of the field. The sensors then send signals to
a processing unit
that is used to correlate the height of the follower within the magazine with
the number of
remaining rounds. The information is transmitted to an active display, which
projects this
information into the first focal plane of the optics train in the main body of
the viewing optic.
The remaining number of rounds is displayed inside the shooter's field of view
within the optic
via the active reticle display.
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system that can display the round count in the magazine from full to an empty
magazine or it
may serve only as an indicator that the shooter is approaching their final
rounds in a magazine.
In one embodiment, the hall effect sensors may reside in a remote that
controls or is
linked to the optic or parts of the optics system. In one embodiment, a new
magazine follower
can be inserted into the magazine.
XIV. Viewing Optic Capable of Integrated Images from Augmented Reality Goggles
Augmented reality goggles are a technology that is currently being developed
to allow
the user to have the capability of seeing information digitally projected into
their field of view
and overlaid on top of what they would normally view through the naked eye.
This could be
anything from target information, to thermal and night vision imaging.
As discussed throughout this application, a viewing optic with an integrated
display
system allows the user to have the capability of seeing information digitally
projected into their
field of view and overlaid on top of what they would normally view through the
optic. In one
embodiment, the disclosure relates to a viewing optic with an integrated
display system that can
integrate images from an augmented reality goggle.
If a user with augmented reality goggles was in a night vision mode, the
entire field of
view is filled with a digital image of the scene in front of the user.
Likewise, a viewing optic
could also display a night vision augmented reality. In this situation, if the
user tried to look
through the viewing optic with an active display, their vision will be
impaired by the digital
image being projected by the augmented reality goggles.
In one embodiment, this disclosure solves this problem by determining when the
viewing
optic with an integrated display system was brought to the user's eye so that
it could either
completely deactivate the digital image projected by the augmented reality
goggles, or disable a
portion of the digital image in the field of view (FOV) of the augmented
reality goggles only
106
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
where the FOV of the viewing optic with an integrated display system would be
covering the
FOV through the augmented reality goggles.
Weapon mounted optics often have a limited area in which the user can clearly
see
through the optic. This area exists as a 3D space comprised of, and determined
by, the exit pupil
and the eye relief. This area is also known as the "eye box."
In one embodiment, the disclosure relates to systems and methods that provide
a user of
augmented reality goggles a way of determining when a viewing optic with an
integrated display
system is brought to the user's eye using a proximity sensor correlating to an
optic's eye box.
In one embodiment, augmented reality goggles could have a proximity sensor
configured
to communicate with a viewing optic having an integrated display system. The
proximity sensor
may vary in its form, function, or technology. When an input from the viewing
optic is received
by the sensor of the augmented reality goggles, the augmented reality goggle
can either
completely deactivate the digital image projected by the goggles or disable a
portion of the
digital image in the field of view (FOV) of the augmented reality goggles. The
input from the
senor could deactivate the augmented reality goggle where the FOV of the
viewing optic with an
integrated display system would overlap the FOV through the augmented reality
goggles. Some
methods to achieve this could use RFID, or other wireless transmitting
methods.
In one embodiment, the disclosure relates to the use of an IR laser mounted to
a viewing
optic with an integrated display system and an IR camera mounted to the
augmented reality
goggles. The IR laser would be aimed back towards the user's augmented reality
goggles. When
the user brought the firearm and the viewing optic with an integrated display
system up to their
eye, the IR laser would hit the IR camera on the augmented reality goggles and
indicate to the
augmented reality goggles that the viewing optic with an integrated display
system was
positioned in front of the user's eye. The augmented reality goggles could be
programmed to
shut off the augmented reality goggle imagery so that the user could then look
through the
viewing optic with an integrated display system.
In another embodiment, the IR laser could also indicate the exact position and
orientation
of the viewing optic with an integrated display system, relative to the
augmented reality goggles.
Using this feature, the augmented reality goggles could be programmed to only
turn off the
imagery in the portion of the field of view that was occluded by the viewing
optic with an
integrated display system.
107
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
This would allow the user to operate with both eyes open and give them a much
larger
field of view for much better situational awareness. The augmented reality
goggles would be
providing the augmented reality imagery for everything outside of FOV of the
viewing optic
with an integrated display system, while the viewing optic with an integrated
display system
would be providing all the augmented reality imagery inside the viewing
optic's field of view.
In another embodiment, the disclosure relates to the use of magnets on or in a
weapon
and a magnetic sensor in an augmented reality goggle system to detect and
measure the presence
of a magnetic field. The sensor and magnet locations may also be reversed. The
sensor would be
calibrated to measure when the user would be within the eye box. When the
sensor detected the
field or the strength of the field that the user was in firing position and
looking through the eye
box, the goggles could shut down all or part of their augmented reality
display so to not interfere
with the viewing optic's FOV.
In another embodiment, the disclosure relates to the use of a pressure switch
mounted to
the stock or the augmented reality goggle system. This pressure sensor could
be mounted on the
top of the stock and be activated by a shooter's check weld. Alternatively,
the pressure sensor
could be mounted on a variety of locations on the stock. If mounted on the
stock, a wireless
transmission could be sent to the goggle indicating that the shooter was in
position to look
through the optic.
The pressure switch may be fixed or adjustable to various shooters, optics
locations,
clothing or other variables. The switch may also allow for a certain pressure
threshold to be
crossed before sending a signal to the augmented reality goggle system.
The pressure sensor could also be integrated into or onto the augmented
reality goggle
system. This may be a placed, moved or calibrated to active when pressed
against the stock when
the shooter is in a firing position looking through the optic.
In all configurations, the system between the viewing optic with an integrated
display
system and the augmented reality goggles could be designed so that the
shooter/user could
shoulder and fire the weapon from their non-dominant/support while having the
augmented
reality display disabled on the appropriate side.
XV. Viewing Optic Displaying Dryfire Feedback
During dry fire practice, shooters practice marksmanship by manipulating,
aiming, and
pulling the trigger on a weapon with either an empty chamber or a non-live
round. In its most
108
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
base form, shooters practice with an empty weapon, aiming at a basic target
reference, on or off a
range. They then observe the weapon movement as the trigger is pulled, but
they have no
feedback beyond their own observations as to whether they would have hit their
intended target
had they fired a live round.
In more advanced configurations, shooters use laser indicators attached to or
inserted into
weapons that give more visual feedback as to muzzle movement as the trigger
breaks for the
shot. These lasers may give feedback as to a hit or miss but only when paired
with very specific
and sometimes expensive target systems.
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system with an active display configured to generate a target onto the
internal screen of the
viewing optic. Sensors can track the movement of the viewing optic to the
internally projected
aim point. The shooter would then dryfire the weapon. Upon the breaking of the
shot, the scope
would give the shooter an indicator that the user would have hit or missed the
projected target
had the user been firing a live round at a physical target.
In one embodiment, the viewing optic can project an aiming or target reference
for the
user; the viewing optic does not have to digitally display an entire target
environment. The user
can then have a digital target overlaid on the image they are receiving though
the optical train in
the main body of the viewing optic. This system will greatly increase the
battery life of the
viewing optic as an entire environment does not need to be recreated and
projected by a digital
display.
In one embodiment, as the main body of the viewing optic has an etched
reticle, no reticle
image is required to be projected onto a display. Additionally, the viewing
optic with an
integrated display system includes onboard atmospheric sensors that can
calculate and
compensate for ballistics, and projected ballistics of a dryfire shot.
Therefore, the shooter can
have their dry fire training account for environmental and atmospheric
conditions that they are
experiencing at the time of the training.
In one embodiment, the viewing optic with an integrated display system has an
active
display that projects an aiming point into the first focal plane of the optics
train of the main body.
The user then moves the weapon system to place a reticle over, or in reference
to, the projected
aiming point in a manner as if the shooter was aiming at a target down range
during a live fire
event.
109
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the viewing optic can use internal or external
accelerometers,
gyroscopes or other sensors to track the physical movement of the viewing
optic in relation to the
internally project image. When the reticle is in a position to take a
simulated shot, the shooter
pulls the trigger. The viewing optic tracks the firing pin impact or movement
using
accelerometers, microphones, gyroscopes or sensors. The shot placement, and
potentially the
follow through, is tracked and measured against the aiming reticles point at
the time of the shot
in relation to the projected aiming point. The system then gives the shooter
an indicator on the
internal display whether as to the shooter would have hit or missed the shot
in a live fire
scenario. The system may provide the shooter information as to where the shot
would have
landed and/or provide instructions as to how the user should correct the shot
placement, or
physical technique used by the shooter.
In another embodiment, the viewing optic with an integrated display system has
an active
display that projects a target that a user can measure using an etched/passive
or active/digital
reticle. The shooter could then utilize holds built into a reticle or dial a
windage and/or elevation
dials to replicate taking a shot at distance.
In another embodiment, the viewing optic with an integrated display system
could
simulate the shooter using a laser range finder to range the projected target.
The shooter could
then apply an appropriate hold or dial windage and/or elevation adjustment to
make a simulated
shot at the specified distance
In one embodiment, the viewing optic with an integrated display system can
monitor
and/or display wind speed, wind direction and other atmospheric changes
including, but not
limited to pressure, altitude, temperatures, humidity, angles, cant,
inclination, Coriolis effect,
spin dift, and down force from helicopter blades.
In another embodiment, the viewing optic with an integrated display system can
include
environmental effects including rain, snow, sleet, or other effects. These
atmospheric and/or
environmental changes may be digitally simulated or gathered from on board
sensors that could
reflect real time conditions that would or could affect ballistics.
In one embodiment, the viewing optic with an integrated display system can
include user
selectable targets for the most applicable application to the shooter. Targets
may be 2d or 3d
images. Examples of targets could include but are not limited to geometric
shapes, traditional
targets shapes (example bowling pins), silhouettes, bullseyes, small game,
medium game, large
110
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
game, birds, water fowl, humans, human silhouettes, enemy combatants, images
of specific
objectives, known or suspected terrorists, high value targets, equipment or
vehicles. The system
may include moving targets including, but not limited to objects what are
moving at the speed of
a target walking, trotting, jogging, running, driving, riding, swimming,
flying or on a pitching
deck of a water craft or vessel. Direction of movement may not be limited to a
single plane but
simulated vertical, horizontal or movement as an oblique may be represented.
Target simulations
may vary in direction and speed.
In another embodiment, the viewing optic with an integrated display system may
or may
not include "shoot" or "no-shoot" scenarios or targets that may be partially
obscured or covered.
Obscured objects/persons/characters may be displayed through image processing.
The system
may display simulated friendly or "no-shoot" units or images. The system may
also network with
other systems so that real friendly systems are displayed within the reticle
so that the user has
"no-shoot" points of reference and/or muzzle awareness indicators so that the
shooter does not
needlessly or unintentionally "flag" or point their weapon at a real "no-
shoot" object.
In one embodiment, the viewing optic with an integrated display system
communicates
hit, miss or other information to the shooter and observers or trainers. This
could be
communicated via audible differentiating between hits or misses. This could
also be
communicating via external light/s that signal a hit or miss through different
colors, pulses, or
light locations.
In one embodiment, the viewing optic with an integrated display system
communicates
with external systems. The information communicated could be feedback giving
hit or miss
indicators or it may show the shooters sight picture at the time that the shot
broke. The
communication link may be unidirectional or omnidirectional. The external
system may be able
to send observer/spotter/trainer corrections, comments, or messages to the
shooter and display
the information within the viewing optic. The communication may be via
physical cords,
wireless signals, network connections, radio frequency or other means of
transmitting data. In
another embodiment, the viewing optic can have a camera that records the
trajectory of the shot.
In another embodiment, the viewing optic with an integrated display system
works and/or
communicates with auxiliary or external systems to create a more in-depth
environment. The
system could work with a thermal unit, night vision, or CEMOS camera that is
connected
physically or digitally to the unit to mimic shooting a target displayed by a
thermal optic or a
111
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
target in no light or low light environment. The system may communicate with a
heads-up
display, or digital screen worn by a shooter to allow for an augmented reality
scenario that
extends beyond the screen of the viewing optic and is additionally mimicked or
displayed by a
user's head mounted system or display interface.
In one embodiment, the viewing optic with an integrated display system may
fire a laser
from a laser system integrated with or connected to the optic upon the trigger
dropping. This
would allow down range sensors or targets to detect the muzzle placement and
orientation upon
the simulated shot.
In one embodiment, the viewing optic with an integrated display system is
placed on a
completely unmodified weapon. The system may be used with or without snap
caps, blanks, or
other simulated or dummy bullets or munitions.
In one embodiment, the viewing optic with an integrated display system allows
the user/
shooter to actively select a dryfire setting via a menu, switch or another
setting selector to active
the program/ dry fire feature of the viewing optic. The viewing optic may
display an alert that
the user has selected a dryfire mode or setting. The viewing optic may have a
program that asks
the user to accept the dryfire setting and may display and/or require the user
to click or verify
firearm safety rules or conditions.
In another embodiment, the viewing optic with an integrated display system is
placed on
a modified or purpose-built weapon. The system may interact with a trigger
sensor to detect a
trigger pull. The system may work with a trigger resetting system that would
prevent the user
from having to manually charge or cock a weapon or trigger system after the
hammer, strikers,
firing pin, or firing mechanism is dropped, initiated, activated or induced.
The system may be
placed on recoil simulating systems that mimic weapon operations via
hydraulics, air, motors, or
other recoil/momentum replication systems, mechanisms, or units.
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system that may allow for additional extremal sensors, connection, devices or
housings to be
placed onto a weapon. These external sensors/systems could link physically,
wirelessly, or
through a network. The additional external sensors could allow for more
accurate movement
measurements. Extra or alternative programs, scenarios, settings controls or
power could be
connected to the unit to allow for a wider variety of training and/ or longer
unit run time.
112
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
External housings or connections could also simulate outside/ external forces
on the physical
weapon.
In another embodiment, the viewing optic with an integrated display system may
have an
additional augmented reality unit attached. The unit could feed information to
the viewing optic
via a physical or wireless connection. This unit may have a camera and/or a
compass so that it
can accurately geo locate and image and place characters onto the proper
location within a
display. The module may not have a separate display but may only feed
information to the
viewing optic's display. The module may act as an image processing unit that
may create and/or
register, among other things, simulated people, bullet impacts, and hit
indicators. Occluded
objects/ images/persons/characters may be displayed through image processing.
In one embodiment, the viewing optic with an integrated display system that
can simulate
real world conditions for a dryfire session does not require an electrical
signal to be sent from the
trigger itself and therefore does not require any modifications to a host
weapon outside of
mounting the optic to the weapon.
In one embodiment, the viewing optic with an integrated display system that
can simulate
real world conditions for a dryfire session will provide shooters with instant
dry fire feedback
without requiring specific external targets. The system does not have to alter
the weight,
handling or balance of a weapon.
In one embodiment, the viewing optic with an integrated display system that
can simulate
real world conditions for a dryfire session can be used by shooters to receive
clear feedback
during dryfire practice. It does not require elaborate target systems to be
set up nor does it have
to project a forward signature. The system does not require any changes to be
made to a host
weapon, and it allows the shooter to practice and become better familiar with
a weapon and
sighting system they would use during live fire events, exercises or
scenarios.
In one embodiment, the viewing optic with an integrated display system that
can simulate
real world conditions for a dryfire session allows for all information to be
internal and does not
require a physical target for any feedback. This system does not require
external attachments and
can be accomplished without changing the weight, balance or handling of
weapon.
In another embodiment, the viewing optic with an integrated display system
that can
simulate real world conditions for a dryfire session may be built as a
dedicated training tool
deferring to, or only featuring, the dry fire functionality.
113
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the viewing optic with an integrated display system that
can simulate
real world conditions for a dryfire session does not require a camera to
capture an image.
XVI. VIEWING OPTIC WITH AN INTEGRATED DISPLAY SYSTEM AND
MULTIPLE USER INTERFACES
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system with user interface technology, which allows the extensive
functionality of the viewing
optic to be easily employed by the user.
In one embodiment, the user interface can be used to navigate and quickly use
an Active
Reticle Scope's features and functions.
In one embodiment, the viewing optic could employ different remote devices to
input
commands or information based on the technologies that are added to a
particular viewing optic.
Ideally, for simplicity, a single button remote would be used, however a multi-
button remote
could be used if enough features were added to the viewing optic. These
remotes could be
physically connected or wireless.
The viewing optic may also communicate with other devices such as smartphones,
tablets, computers, watches or any other devices, which provide information or
functionality to
the viewing optic. These devices could communicate wirelessly or through a
physical
connection.
In one embodiment, the viewing optic could also or alternatively receive and
execute
commands input by the user through voice commands. The scope may have a
microphone or it
may be linked to a communication system already used by the shooter. The scope
could also
integrate eye tracking technology that would allow the user to navigate and/or
perform functions
in the optic.
In one embodiment, the viewing optic with an integrated display system can
have ranging
targets as well as tagging target capabilities. As discussed above, the
viewing optic with an
integrated display system can be used to "tag" a target. If a single button
remote is used there
needs to be a way for the user to distinguish from tagging a target and
ranging a target.
In one embodiment, for ranging a target, the user would simply tap the single
button on
the remote. This would tell the viewing optic with an integrated display
system to fire a laser
pulse and measure the range to the target and display a ballistic solution and
hold point. For
tagging a target, the user would push and hold the single button. As the
button was being held,
the display would show a short animation that would indicate to the user that
the tagging
114
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
function was activated. For example, the user might see a shape being drawn in
the center of the
field of view where they were pointing the viewing optic. Once the shape
finished drawing the
user could release the button and this would communicate to the viewing optic
that the user
wanted to tag the target currently covered by the drawn shape.
Immediately upon button release a menu would appear that would give the user
multiple
selections to label the type of target that the user just tagged. For example,
the selections could
include, but are not limited to: Enemy, Friendly, Waypoint, Unknown, etc. The
user could cycle
through the selections using the single remote button with single taps and
then select a target
with a press and hold, or the user would have the option of using the 5-button
pad on the viewing
optic to navigate the menu and make a selection.
Once a target was tagged and labeled the display would show a symbol in the
user's field
of view. The shape could indicate to the user what type of target it was for
them to quickly
identify. In one embodiment, the menu can request confirmation of the correct
tag.
There is also a need for a user to be able to change or delete a target. To do
this, the user
would press and hold the remote button and wait for the tagging symbol to be
drawn. Once the
tagging symbol was drawn, and without releasing the button, the user would
simply move the
viewing optic so that the tagging symbol was covering or touching an existing
tagged target
symbol and then release the button. Upon button release a menu would appear
that would list the
target types, as well as a delete option. The user could cycle through the
selections using the
single remote button with single taps and then select a target with a press
and hold, or the user
would have the option of using the 5-button pad on the viewing optic to
navigate the menu and
make a selection.
In one embodiment, the viewing optic with an integrated display system has the
ability to
indicate Close Proximity Target Tags. When tagging targets in very close
proximity to one
another, the system may mistake an attempt to designate a new target, as the
selection of a
previously marked target. When the menu is displayed for the previously marked
target, an
option would appear that would allow the marking of a new target. The user
could press and
hold to select this option or use the 5-button pad on the viewing optic to
make the selection. The
user would then be prompted to select the target label they desire for the new
target.
In one embodiment, the viewing optic with an integrated display system can
have the
ability to display coordinates. In one embodiment, the viewing optic may have,
or be paired with
115
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
a laser rangefinder, a compass and a GPS unit. These features may provide the
functionality to
provide the user with coordinates for tagged targets. This feature could be
very useful for
establishing rally points, directing air support, coordinating artillery fire
or other applications.
Full and constant coordinate display may not be desired by users though as it
may clutter a
display.
In one embodiment, full customizable options may be available through a deep
menu
option, or through a computer or other more advanced interface technology. In
one embodiment,
the default settings could be streamlined to users with only a remote. Certain
target tag label
selections, such as rendezvous points or air strike locations, could always
have a coordinate
displayed adjacent to a target marker.
Alternatively, some or all of the target tags labels may only display the
coordinates when
the optic's reticle is hovering over the target tag for more than a few of
seconds. The coordinates
could be displayed adjacent to the target tag or in another part of the
viewing optic. The display
could be passive and be displayed automatically or it could require a button
press combination to
display the coordinate. The same press combination could remove a displayed
coordinate from
the screen. The duration of the coordinate display could be determined by a
user in a separate
menu option.
XVII. VIEWING OPTIC WITH A TURRET TRACKING SYSTEM
Adjusting an optic's reticle typically involves dialing a turret, which moves
an optic's
aiming reticle up or down or side to side a specific number of units, usually
mil radians (mils) or
minutes of angle (MOA). These units are usually defined by small detents and
often make small
audible and tactile "clicks."
Certain turrets can allow for greater than 360 of rotation. This benefits the
shooter as
they have access to a greater adjustment range. For example, if a single
rotation will move a
reticle 5 mils, two full rotations would allow for 10 mils of adjustment. This
significantly
extends this distance a shooter can engage a target while using the reticle as
an aiming reference.
Without a clear reference though, a shooter can quickly become confused as to
which rotation is
currently on. This problem is further exacerbated when a shooter has 3, 4, or
more than four
rotations of adjustments available to them.
Some scopes feature reference lines on their turret. As the turret is rotated,
the body of
the turret head would raise and expose horizontal reference lines. However,
these lines are small
116
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
and hard to see from behind a firearm under even the best conditions. In no
light or low light
environments, there is no good way for a shooter to observe their turret
revolution without using
a light source to illuminate the turret. For some hunting, law enforcement and
military scenarios
this is not a feasible option.
One alternative is to have a revolution indicator installed on the scope.
Often these
indicators consist of a physical pin that slowly protrudes from the optic as
the turret rotates. The
changing pin height gives the shooter a reference point as to the turret
rotation when using the
optic in low light or no light conditions, but it does not easily provide a
distinct reading as to the
exact turret adjustment. For example, a scope may have a pin that protrudes on
the second
rotation, but the user may not know if they are dialed at 11.1 mils or 17.3
mils on a turret that has
mils of adjustment per rotation. These values will result in substantially
different points of
impact, particularly if the shooter is engaging a target at mid to long range
distances.
Using a revolution indicator also means the shooter must physically feel their
optic to
know their turret setting. This would require the shooter to break their
firing position by moving
either their firing or support hands from their respective positions. This is
not an acceptable
solution when a shooter may need to engage a target at a moment's notice.
In one embodiment, the disclosure relates to a method to track the turret
adjustments of a
viewing optic whereby the components of the tracking mechanism are reliable,
transparent to the
operator, and environmentally protected. The turret tracking system disclosed
herein employs an
LED, a photosensor and a strip of material that has varying degrees of optical
reflectance/absorption.
In one embodiment, the turret information can be transmitted to an active
display, which
can then project the turret information into the first focal plane of the
viewing optic with an
integrated display system.
In one embodiment, the turret tracking system disclosed herein provides users
with an
easy to read display of their current adjusted value of an optic turret. In
one embodiment, the
disclosure relates to a viewing optic with an integrated display system and a
turret position
tracking system comprising an LED, a photosensor and a strip of material that
has varying
degrees of optical reflectance/absorption. The sensor then transmits data to
an active display of
an integrated display system, which projects the information into the first
focal plane of the
optical train of the main body.
117
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the turret tracking system may be used on
elevation/vertical
adjustment, windage/horizontal adjustment turrets and/or any other rotating
adjustment on or in a
viewing optic.
FIGS. 88 and 89 are representative depictions of a turret tracking system.
FIG. 88 is a
representative depiction of a printed circuit board 8805 with micorprocessor,
photosensor and
LED 8810 and a simulated cone of vision drawn to illustrate the angle of
acceptance of light for
the photosensor. FIG/ 89 is a representative depiction of a turret 8905 with
material having a
grayscale gradient 8910.
In one embodiment, the viewing optic has one or more turrets 8905 having a
turret
tracking system with an the LED and photosensor 8810 housed within a fixed
position inside the
turret. When the turret 8905 is rotated by the operator, an erector tube is
moved, which changes
the position of the optic's reticle. Affixed to the inside diameter of the
turret is a material 8910.
In one embodiment, the material 8910 is approximately lOmm wide and 40mm long.
The
material may cover 360 of the turret 8905. One side of this material 8910 has
an adhesive that
is used to attach it to the interior turret wall. The other side of the
material 8910 has a printed
grayscale gradient on it which, when an LED is shone on it, will reflect
varying amounts of light
depending on which portion of the gradient is being exposed to the LED.
The LED illuminates the gradient strip and the photosensor receives a portion
of the light
reflected off the gradient strip, and sends a signal to a microcontroller, the
strength of the signal
varying with the amount of light detected. When an adjustment turret is
rotated by the operator a
different portion of the gradient strip is exposed to the LED and photosensor
which in turn
changes the signal strength sent to the microcontroller. The turret setting of
the system is
therefore able to be tracked by associating it with the amount of light
detected by the
photosensor. This information is then sent from a microcontroller, for
example, to an active
display within the integrated display system of the viewing optic, which gives
the user a value
correlating to the turret position. This value may correlate to the exterior
reading of the turret.
In another embodiment, the reflective material can be fixed in position and
the
photosensor and LED can rotate around the reflective material.
In another embodiment, the LED and sensor may be located outside of the turret
and the
reflective material is affixed to the exterior of a turret mechanism. This
design may be beneficial
to protect against outside elements.
118
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the turret tracking system may reside inside and/or outside
the
viewing optic body. In one embodiment, the turret tracking system may reside
within and/or
outside a turret body and may be part of the turret.
In one embodiment, the turret tracking system may be a module residing with or
next to
the optic turrets.
In another embodiment, the reflective gradient strip may have defined
sections, or may
have infinitely varying reflectivity. The reflective material may be attached
to the viewing optic
and/or turret or it may be integrated into the viewing optic, turret body,
housing, coating or
another element. If the reflective gradient has defined sections, those
sections may correlate
and/or match to the rotation and/or click adjust of the physical turret
mechanism.
In another embodiment the reflective material has two or more alternating
levels of
reflectivity. The sensor would then track the changes and send the information
to a processor,
which would "count" the number of changes to provide a value to the display.
In one embodiment, the turret tracking system may also "count" or track full
revolutions
to allow the display of an adjustment past a single rotation. In another
embodiment the material
may be finely calibrated and/or have reference marks and the material or the
sensor may move
up or down with or on an erector tube to allow for a greater spectrum of
reflectivity so which
could allow the system to sense/read multiple turret rotations.
In one embodiment, the turret display may remain visible at all times or it
may only be
displayed when the shooter has dialed an adjustment that is not their zero.
The turret display
options may be user selectable. Turret values may be displayed using numerical
values, words,
acronyms, symbols, graphics or other methods. The display settings may be user
adjustable. The
display may show turret and unit references.
In one embodiment, the displayed units of angular measurement are usable
selectable that
could include, but are not limited to mil radians (mRad or mils), Minutes of
Angle (MOA),
Gunners Mils or Shooter's MOA. This would allow for the shooter to work with
spotter elements
who are giving corrections in another unit.
For example, if a marksman had a scope with 0.1 mRad adjustment turrets, and
an mRad
calibrated reticle, the spotter may be giving feedback in MOA. The shooter
could then switch
their optic to digitally display the units in MOA. As the viewing optic cannot
change the
physical adjustments increment, the optic would do a unit conversion for the
shooter.
119
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
For this example, 1 MOA = .30 mils. If the spotter told the shooter they were
low by 2
MOA, the shooter could then switch their displayed units to MOA. The shooter
would dial their
adjustment. The scope turret could read + . lmil ¨> .2 mil ¨> .3 mil¨ > .4
mil¨ > .5 mil ¨> .6 mil.
While dialing the internal displayed adjustment could read + .34 MOA ¨> .68
MOA
1.02 MOA¨ > 1.36 MOA 1.7 MOA ¨> 2.04 MOA. This would allow the shooter to
make
their adjustments off another unit of angular measurement.
In another embodiment, the viewing optic having an integrated display system
and a
turret tracking system could communicate with a laser range finder and a
ballistic calculator to
provide corrections in units of linear measurement rather than units of
angular measurement.
These units could include, but are not limited to, inches, feet, yards,
millimeters, centimeters, and
meters. As the optic itself cannot change the physical adjustments increment,
the optic would do
the unit conversion for the shooter based on the given distance to the target
and the ballistic
profile of the projectile.
For this example, 0.1 mil is .36" at 100 yards. The shooter could switch their
viewing
optic to display units in inches and the shooter could measure the distance to
the target. The
distance could be entered into a scope menu, or measured and automatically
input by a laser
range finder that could be connected physically or wirelessly to the optic.
If the shooter was 1.5 inches low at 100 yards the shooter would dial their
adjustment.
The scope turret could read + . lmil ¨> .2 mil ¨> .3 mil¨ > .4 mil. When
dialing, the displayed
adjustment, provided by the active display and projected into the first focal
plane of the optical
train, could read + .36inches¨> .72 inches ¨> 1.08 inches¨> 1.44 inches. This
would allow the
shooter to make their adjustments based off units of linear measurement.
In one embodiment, the viewing optic having an integrated display system and a
turret
tracking system could display units that correlate to weapon profile zeros
stored in the viewing
optic menu. These weapon profiles could contain zero information, ballistic
software and/or data
and other auxiliary information that could be used by a shooter to help
successfully calculate
and/or conduct a shot. This may be integrated with or without a physical
turret zero stop. This
feature could be used with switch caliber weapons, switch barrel weapons,
different ammo loads,
with or without silencers/sound suppressors, when moved to different weapon
platforms or in
any other circumstance when the shooter has different zeros.
120
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
For example, a shooter could have a switch cartridge/caliber/barrel rifle with
a 26-inch
.300 Norma barrel shooting a 230-grain bullet and an 18-inch 7.62x51 NATO
barrel shooting a
175-grain bullet. These two barrels would have substantially different
velocities and ballistics. If
a shooter zeroed their optic with the .300 Norma at 100m and then switched
barrels to the 7.62
NATO round and shot the weapon again at 100 m the shooter would find their
rounds would not
impact in the same spot. For the sake of the example, the 7.62 NATO load was
1.3 mils low and
.4 mils to the left when shooting at 100 meters after zeroing with the 300
Norma.
The shooter could choose to reset the zero of the scope, but that could
compromise the
.300 Norma zero and the process could prove tedious if the shooter must switch
cartridges on a
frequent basis.
The shooter could choose to maintain the .300 Norma zero and just dial for the
distance,
but the shooter would then have to be cognizant of the required adjustment for
the zero. For
example, if the shooter had to dial for a shot that required 5.2 mils of
adjustment, their final
turret reading would be 6.5 mils (5.2 mils would be for the new shot, and 1.3
would be the
correction for the 100-yard zero). Additionally, when the shooter returned
their scope to their
zero setting after taking the shot, they would need to remember to stop at 1.3
mils, not at 0 mils.
Finally, the shooter could try to zero the cartridges at distances that
correlated to their
bullet drop, but this rarely corresponds to round, easy to remember,
distances. The shooter may
zero the 7.62 NATO at 100m but the .300 Norma may be zeroed at 217m. This is
not convenient
when the shooter is trying to shoot and make corrections quickly, and it does
not account for any
shift in the windage correction/ horizontal direction when switching between
the two zeros.
In one embodiment, the viewing optic having an integrated display system and a
turret
tracking system could use saved weapon profiles to solve these issues. For
example, the shooter
could set their mechanical zero for the .300 Norma. The optics weapon profile
for the .300 would
save/ preserve that zero in its memory. The interior display could read zero,
or display 0
elevation and/or 0 wind, or any other written or graphical indication as the
turret status to include
abbreviations, arrows, symbols, tic marks, or markings on an etched, passive,
active or digital
reticle. The display or optic may or may not include which weapon profile is
selected.
The shooter could conduct a barrel change to the 7.62 NATO, and then select a
saved
weapon profile for the new barrel. Once the appropriate weapon profile is
selected, the scope
display would show that the user was currently 1.3 mils low and .4 mils to the
left of the barrel's
121
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
zero. The shooter could then dial the turrets to those settings and the
display could show the optic
was zeroed for that profile. The shooter could then take their shot that
required 5.2 mils of
adjustment. After dialing the turret for the bullet drop, the internals could
display 5.2 mils above
zero to the shooter. The physical turrets could show that there 6.5 mils
dialed, but the shooter
would not have to remember the 1.3 mil correction as it could be stored inside
the optic's
memory/ program. Instead, the shooter could use the digital zero for that
weapon profile as a
reference points for all future shots regardless of the mechanical zero so
long as there was
enough travel in the scope dials to make the adjustment/correction.
In another embodiment the viewing optic having an integrated display system
and a turret
tracking system may account for variables resulting from being placed on,
connected to, or
integrated with an adjustable base, rail, mount or fixture. Any additional
angle, cant, incline or
other variable induced in any direction by the fixture may be input through a
user interface or it
may be accounted for automatically through a physical or wireless connection.
The viewing optic
having an integrated display system and a turret tracking system may store
and/or project this
information in the display using numerical values, words, acronyms, symbols,
graphics or other
methods. This information can be shown as a single sum that includes both
optic dial
adjustments and the angle or variable induced by the fixture. Alternatively,
this information may
be displayed separately with a total sum that may or may not be included.
An example of this would be when using the viewing optic having an integrated
display
system and a turret tracking system attached to an adjustable base for the
firearm or weapon. A
shooter could zero their optic with the firearm base imparting zero MOA. At
such time, the
internal display would show the shooter was at their zero. To gain additional
elevation travel, the
shooter may apply an additional 20 MOA through the adjustable firearm base. No
adjustments
would have been made within the viewing optic but the reticle now has a 20 MOA
incline. The
shooter could input this information into the viewing optic. After the input,
the viewing optic
having an integrated display system and a turret tracking system could display
that the shooter
was at 20 MOA, rather than at the weapon's zero. If the shooter needed to then
fire at a target
using a 25 MOA correction, the shooter would dial 5 MOA into the scope for a
total of 25 MOA.
MOA from the scope and 20 MOA from the firearm base.
In another embodiment, the viewing optic having an integrated display system
and a
turret tracking system may transmit the displayed information to another user
such as, but not
122
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
limited to spotters, trainers, hunting guides, or range officers. This could
allow for other clear
communication between two or more different parties. The information could be
transmitted
through a physical, wireless, network, radio, or other communication means.
The information
could be displayed in other optics, cell phones, tablets, computers, watches
or any other devices.
In another embodiment, the viewing optic having an integrated display system
and a
turret tracking system can use an additional light sensor, or proximity sensor
or other sensor to
indicate when or if a turret lock was engaged. This information could be
displayed within the
optics display. This information could be displayed using numerical values,
words, acronyms,
symbols, graphics or other methods.
In another embodiment, the viewing optic having an integrated display system
and a
turret tracking system allows the shooter to see the dialed adjustment/s
without having to break
concentration from a sight picture by displaying the value/s within the
display of an active reticle
optic. Additionally, the shooter is not required to break their shooting
position to manually feel a
dial, knob, or other form of turret position or rotation indication.
In one embodiment, the disclosure relates to a viewing optic comprising: a
main body
with an optical system having a moveable optical element configured to
generate an image of an
outward scene, a turret configured to adjust of the moveable optical element,
wherein the turret
has (a) a material with varying degrees of optical absorption/reflectance
coupled to a portion of
the turret and (b) a photosensor configured to detect light reflected from the
material, wherein the
amount of light detected in indicative of turret position and a beam combiner
and an active
display in communication with the photosensor and configured to generate an
image indicating
turret position for simultaneous viewing of the generated image and image of
the outward scene
in a first focal plane of the optical system.
In one embodiment, the disclosure relates to a viewing optic comprising: (i) a

the generated
image and image of the outward scene in a first focal plane of the optical
system.
XVIII. A VIEWING OPTIC CAPABLE OF GENERATING AND DISPLAYING
AN ENGAGEMENT WINDOW
Urban snipers may use "loop holes" (a small hole through a barrier) to keep
themselves
in cover while still being able to precisely engage a target. With some basic
math, a shooter can
adjust their optic to shoot through one of these holes at a given distance and
place precision fire
on a target at a further range.
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system that can display an engagement window using the loop hole size, and
other loop hole
characteristics including but not limited to the distance to the loop hole, a
weapon's physical
characteristics, ballistic data of the projectile and weapon system, and
atmospherics measured
by, or input into, the viewing optic. The viewing optic can provide multiple
wind and elevation
hold marks as well as boundary marks for internal dimensions of a measured
loop hole.
In one embodiment, the disclosure relate to a viewing optic with an integrated
display
system that can be used to shoot through a loophole, which is considerably
easier and safer than
other systems. Shooters engaging a target can experience a height over bore
effect. Height over
bore is the difference in height between the barrel of a weapon and the center
of the aiming
device, be that iron sights, a magnified optic, a red dot, or another aiming
mechanism. When
shooting in tight confines, and under stress, the shooter may be able to see a
target through their
aiming mechanism, but their barrel or bore doesn't clear an obstruction.
For example, a shooter may try to engage a target over the hood of a car. The
shooter,
attempting to keep as low as possible may be able to see their target through
their sights, but
their muzzle may not clear the car. Because of the difference in height over
bore, instead of
bullets hitting the target when the shooter fires what they think is a clear
shot through their
sights, the bullet/s instead hit the car hood. This height over bore effect
can be further
magnified by a shooter attempting to take shots at a long distance due to the
angles of the
weapon system.
In one embodiment, a viewing optic with an integrated display system makes
this process
considerably easier for the shooter by displaying a digital box within their
optic that represents
the area the shooter can successfully engage the target through the loophole.
124
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
In one embodiment, the viewing optic with an integrated display system is
configurable
to a multitude of host weapons, with varying height over bores, accounts for
vertical and
horizonal constraints, and accounts for ballistic drop at a variety of
distances.
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system that can generate an engagement window customizable via user's personal
ballistic
information, loop hole size, and distance to loop hole. In one embodiment, the
active display can
project the engagement window into a first focal plane and can provide
boundary marks as well
as multiple wind and elevation hold marks for targets through the loophole.
Shooting through loop holes is a practice achieved by using the principle of a
Near Zero
and a Far Zero. FIG. 90 is a representative schematic of the Near Zero and a
Far Zero concept.
In one embodiment, a viewing optic with an integrated display system can
calculate near
and far zeros, and account for height over bore, thereby allowing a shooter to
more easily shoot
through a loophole to engage a target at a much longer distance.
In one embodiment, the disclosure relates to a viewing optic with an
integrated display
system, wherein the active display projects a window, which is based on the
calculations
mentioned in the preceding paragraphs, through which a shooter can use near
and far range zeros
to engage a target. This window may be based off the measurement of the scope
height over the
bore, the distance to the loophole, the size and depth of the loophole,
atmospherics, ballistic data
of the projectile, angles, cant, projectile caliber/diameter, weapon/shooter
accuracy and/or any
other factors that may affect a shooter's target engagement. This box may be
adjusted in tandem
with elevation/vertical and/or windage/horizontal turret adjustments. The
boundary marks may
be any number of colors, line thicknesses, and may be dashed or solid. The
optic may use
accelerometers or other sensors to track the engagement window location while
the scope is
physically moved.
When the shooter is pointed at an area that would cause an impact rather than
a
successful engagement through the loophole, the viewing optic with an
integrated display system
will give the shooter a warning message. This message could be written, or
displayed in
graphics. There may be an indicator on the reticle/s that shows the shooter
they would be
unsuccessful in shooting through the loophole.
In one embodiment, the shooter inputs the dimensions, orientation and the
distance to the
loophole into a program or menu within the viewing optic. The viewing optic
via one or more
125
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
processing units/microcontrollers could keep standard shapes that the shooter
could use to
describe the loophole. The viewing optic could also allow the shooter to enter
length and angle
measurements of the opening to better customize their loophole boundary
display.
In another embodiment, the shooter could use a laser range finder to get the
distance to
the loophole. The viewing optic could also allow the shooter to "trace" the
outline of the
loophole within the scope. This could be drawing the loophole on the display
using a keypad or
another interfacing control device. The viewing optic could also allow the
shooter to track the
movement of the optic as the shooter "traces" the loophole outline with a
reticle/s or tracing
point.
In another embodiment, the viewing optic could use cameras that would be able
to "see"
the loophole. The shooter could have the cameras register the opening and
display the shoot
window within the optic. The cameras could track the shooters movement so that
if the shooters
height, distance or angle to the loophole changed the camera could
automatically track the
changes and display an updated shoot window within the optic.
In another embodiment, the viewing optic could create a custom bullet drop
compensating (BDC) reticle that could be displayed in the optic. The BDC could
display ranges
that the shooter could successfully engage a target through the loophole as
well as appropriate
wind holds to a target.
In one embodiment, the viewing optic could allow for atmospherics to be
gathered from
sensors on/ in the optic, sensors outside the optic to include sensors outside
the loophole, or
atmospherics could be entered into the optic by the shooter via a menu and
keypad or another
interfacing control device.
In another embodiment, if the shooter attempted to dial or hold for a shot
that was outside
of the loophole, the viewing optic could give the shooter directions as to how
the shooter could
successfully engage the target. The viewing optic could tell the shooter to
move their shooting
position left if there was not enough horizontal distance in the loophole to
engage the target they
wanted to shoot. These directions could be written, displayed in symbols,
graphics, audible
through communications gear, or they could be communicated through other
methods. These
directions could be displayed within the optic or transmitted to other
communication devices.
In another embodiment, the viewing optic could be paired with a programable
bipod,
tripod, chassis, support system, or device that could allow the weapon to
swing, move or pivot
126
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
the weapon system within the shooting loophole angles. The support device
could use rails,
pivoting or panning supports, articulating balls or other mechanisms that
could both support and
allow the movement of the weapon system. The support device could fully
support the weapon
or require additional support from the shooter. The device could feature
programmable stops that
could prevent the weapon from engaging targets outside the window. The
rotation or travel stops
may be input/set by the shooter or through communication with the optic. The
support device
could be linked physically to the optic or wirelessly. The support device
could be manually
controlled or controlled via motors or electronics.
XIX. PROTECTIVE SHIELD FOR A LENS
Lenses on optical systems can easy become scratched, which reduces the users'
image
quality. Some lenses are also fragile enough to fracture, break or shatter
when impacted. To
prevent damage to lenses, users often use optic covers on their systems.
While optics covers help protect the lenses they can often be slow to deploy
or remove. It
is also common for covers to negatively affect image quality by reducing
clarity, distorting
colors, creating the feeling of a tube effect or by restricting or blocking
light to the user.
In one embodiment, the disclosure relates to a protective window to protect
exterior
lenses. With the protective window, users will eliminate deployment time issue
and image
quality should be minimally affected, if affected at all, in comparison to a
system with no covers.
In one embodiment, the disclosure relates to an integrated transparent shield
to protect the
exterior lenses of a viewing optic. This window may be made of glass, acrylic,
polymer, ceramic,
Nano grain structured elements, or other clear mediums. The window may have
additional
coatings applied to increase hardness, improve scratch resistance, increase
water repellence,
reduce color distortion or otherwise increase desirable characteristics and
minimize undesirable
affects.
In one embodiment, the transparent shield is part of a sealed and/or purged
optical
system. In one embodiment, the shield may be held in place by any suitable
method including
but not limited to being held by grooves sealed by 0-Rings, adhesives, or
other methods that
could preserve an airtight seal for an optical system.
In another embodiment, the transparent shield may exist in front of a sealed
optical
system so that the window could be removed or replaced. Replacing the window
could be for
the purposes of replacement in case of damage, using different coatings for
optimum light
127
CA 03108899 2021-02-05
WO 2020/101768 PCT/US2019/045493
filtration, changing window tints or colors, insertion or removal of a
polarized window or other
reasons. This window could be held in place by snaps, detents, grooves,
threads or another
method that could allow for the extraction and replacement of the window while
withstanding
the burdens placed on the optic, such as recoil.
In one embodiment, the transparent shield can be any shape including a round
shape.
The shield can be sized and shaped to best fit the needs of the protected
optical system.
In one embodiment, the shield can be used to protect forward or rear facing
lenses.
